Foreword Because often running and afraid of suffering from "after running injury" would like to add a bracelet to see the relevant information, search Jingdong distribution 200 within the distribution of the top five heart rate bracelets are millet (MI) millet bracelet 2 , Weloop only Music Now2 , millet (MI) light version , bong 3 HR star, music mambo HR . Excluding the music heart and music that can not be real-time heart rate, the remaining millet 2 support information not support content display, and bong3 more than the millet 2 also has a number of blood oxygen monitoring and speed display function, although no use but feel more Applicable to the appearance of running. So regardless of the poor evaluation of the previous generation bong2 and bongX into this bong3 Star Edition. Speaking of this review, I would also like to thank Zhang Aunt and you, because the purchase of the bracelet's money comes from the station rewards and the 200 Jingdong shopping card that you can use to exchange for gold coins. At the same time also received a Jingdong 200 minus 10 full-category vouchers (do not want to scrap the single can also receive 100 minus 5), manufacturers often have reduced 10 activities. The delivery is still very fast. At 11:00 on the day of the order, it will arrive at 16:00 on the same day. The first time I was fully charged, I ran more than 100 kilometers within two weeks. I felt good, so I went back and sorted out some data to write this evaluation as objectively as possible to thank everyone for the gold coins. The other three less than two hundred yuan bracelet is certainly not bad, except for sports, pedometer, sleep, and information reminders; Xiaomi 2's mobile phone unlock is convenient for users with Xiaomi mobile phone and app support is better. The basic functions that are willing to have all have the lowest price for users who are in contact with the wristband. The only touch screen operation and find the mobile phone and other functions are more suitable for users with more needs, the specific site can see the original I will not talk about it. First Picture After Text Below Text Starts First, appearance Connecting to the app for the first time will show the upgrade. Second, function This wristband mainly feeds back the following four functions, namely, exercise , sleep, information reminding and battery life. The number of steps, distances, calories, and heart rate in the wristband can be recorded independently in the wristband without relying on the iphone. At least ten days or more can be imported into the mobile phone at a later stage, but I changed it two days later. Android phone forgot to match the bracelet, the two days of data can not be synchronized to the iphone phone, and I do not know why. 1. Sports The heart rate of the wristband is higher than my expectations, but blood oxygen and static heart rate are just a matter of choice. Really wanting to know the data is not as good as it is. Overall, I am very satisfied with the real-time heart rate, operability, and automatic display of information. 2. Sleep data 3. Information display 4. Life time For the first time, about 60% of the original machine's electricity is charged to 99% and it will take a little while, and the remaining 1% is more than half an hour. It takes more than 90 minutes to reach 100%. It took 110 minutes to charge from 2% to 100%, and it took 120 minutes from 18% to 100% for the third time . These three times are all very slow with the last 1% charge. Eventually, the bracelet was shut down from 16 o'clock on the 3rd to 15 o'clock on the 17th and used for a total of 14 days. If you turn off the daily alarm clock and turn off the automatic heart rate test, the two large power consumers and the lesser number of steps, you can easily achieve the official 20-day battery life. If you have less information on the phone, you can even maintain a longer time. Significantly charged.) other: Alarm clock: The wristband must be connected when setting the alarm, and then it will vibrate periodically without connecting the phone. That is to say, even if the mobile phone is turned off, the alarm clock will vibrate when it is time to stop. The method of stopping the alarm clock shakes the wrist twice as if the call alert is stopped. This is helpful for people who want to get up regularly and do not want to wake the pillow. entertainment: The mobile phone app has a small design of an electronic pet at the bottom of the data report page. The game is similar to the electronic chick that was popular as a child, that is, it is necessary to exchange food for small bong dragons with uninterrupted exercise steps. FAQ: Do you need to bring a mobile phone to run a bracelet? - If you do not have a mobile phone, the heart rate and distance in the bracelet can be kept and synchronized later. Because I am accustomed to running laps and fearing that I missed the phone, I will run with a mobile phone. Wearing a breathable belt bag, arm bag, or tight-fitted phone with storage will not affect the running results. Is the bracelet suitable for running marathons or other professional sports? - The distance recorded by the wristband and the pace are not accurate. Unless you convert it yourself, it is okay to deal with it occasionally. However, ordinary people who do not have systematic training do not recommend to run directly. . . (Saying a small case, Pharaoh next door, who was running with me in the park a year ago, was only able to run for 2km. Half a year later he ran half a horse. Now that Pharaoh is still running, he has already had knee pads to do restorative exercises. ...) Is the bracelet's heart rate accurate? - The static heart rate is inaccurate, and exercise heart rate is relatively accurate because it is a long time heart rate and then averaged. Assume that the accuracy rate of the heart rate band is 95%, and the accuracy of the heart rate bracelet is at least 90%, which is enough for daily running. Why do you want to see heart rate? - When the heart rate is too low during exercise, there is no exercise effect, and if it is too high, the body will be injured. So heart rate as an important criterion of exercise intensity can let you know what state it should go to. (How many heart rates are appropriate vary from person to person, and can be found specifically What is the use of the bracelet showing the pace? - One of the key points of non-athletic and healthy running is uniform speed. Speeding is to find the speed that is right for you. Early control of good heart rate, breathing, and step frequency is gradually increasing the pace. Why not use a more accurate heart rate band? - Wear troubles. In addition, if you want to see the heart rate while running, you must use your mobile phone to influence the running rhythm. Looking at the heart rate afterwards will not help. I think that as long as a healthy person runs, 5% heart rate error can be ignored. Why don't you buy a heart rate watch? - The heart rate watch is expensive, it is not as comfortable as a wristband, it is frequently charged, and its appearance is heavy. The most important thing is that most gorgeous features are not available. For example, my wife once asked me if you bought a watch with GPS and barometric pressure for running. On it? Are you afraid of running lost? Do you want to compare weather forecast accuracy with weather bureau? ...I was speechless. But outdoor cross-country must be equipped with a reliable outdoor table, and sometimes it can be renewed. Finally, make a small summary, the disadvantages are more, I hope the official can pay attention Shortcomings The most important! ! ! The distance calculation is very inaccurate, and you have to recalculate it. The current algorithm version number is v2016060919. You are looking forward to adjusting the algorithm settings based on personal data. Secondly! ! Wrist gestures are not very sensitive. Fortunately, there are not many wrists. once again! When the outdoor lighting is good, the screen cannot be clearly seen even when it is highlighted, and shadows need to be obscured and carefully identified. It is hoped that the battery performance will be enhanced and the display brightness will be enhanced. Want to increase the pace display It is inconvenient to remove the main unit when charging. Static heart rate and blood oxygen sensation are inaccurate. This hope has a more professional evaluation to illustrate. Hope to support more APP readings, such as Run Run, Runtastic and the like. advantage It is very easy to use several functions for running, and it can be felt that the runners do it. Life time is enough Wear comfortable, wash your face without having to pick END Educational Instrument;Student experimental equipment;laboratory training Wuxi Lerin New Energy Technology Co.,Ltd. , https://www.lerin-tech.com
The Bong3 Star Edition is the same as the cool black version except that the packing box and the wristband have different appearances. 
The box has a host of bong3, a wristband with a blue print, a charging base, and instruction paper. The green light of the heart rate test is also activated automatically when the host computer comes out. After charging, insert the wristband from the back side, and the host card will not be shaken off. 
The back of the machine is printed with Hangzhou attacking shell design and daily waterproof lettering (officially known as IP67 - anti-short time soaking under normal temperature and pressure, when the shell is temporarily immersed in 1M deep water will not cause harmful effects). The following is a slightly concave heart rate oximetry window. There is a curvature of the wrist attached to the back so there is no obvious impression after wearing. 
Starry wristbands feel better than black wristbands, and there are some more fancy wristbands for sisters that are hard to buy. 
The host needs to be removed from the wristband and put into the cradle during charging (this is more troublesome but may be waterproof). At the same time, Bluetooth can connect to the mobile phone for binding, setting and other actions, and the Bluetooth connection is also stable afterwards. There is no problem in the connection distance. Mobile phone alerts can be received in every room. It is automatic to disconnect and connect smoothly. (Want to learn about Bluetooth's searchable nordic cortex M4 Bluetooth chip article) 
Various displays before the 2.0 version of the bracelet can also be set to the landscape display mode according to personal habits. 
You can display day, month, week and time information directly by lifting your wrist or double-clicking the screen. The success rate is 99%. Switching the number of steps, distances, and heart rate information can only be switched using this method. I feel that there is a sudden turn of the wrist to master the power or the success rate is 60%. Too much trouble can be displayed in the app terminal and the control interface is set to an automatic switching mode, so that lifting the wrist can automatically display the above content in turn, but this will also take time to spend electricity. 
There has been an important upgrade in the later period. The firmware of the bracelet is up to version 2.12. It is highly recommended to update it. 
Calorie and weather, temperature, and PM2.5 are displayed after the update, which can reduce the number of times that the mobile phone is viewed. But the weather shows that it cannot be disconnected from the phone otherwise it will be displayed Please connect bong app 
Get started feeling; medical grade TPE material used in the wristband, because there is no sweat guide slot on the reverse side, so the wristband is thicker and overall harder. Before the friends who played the millet 2 feel wristband soft elastic big friend also said that wearing a long time is easy to loose, this Bong3 wristband gives a more real feeling. Usually, you can wear loose, and you will get stuck when the heart rate increases. There is no problem with the sense of wearing. I don't feel like I don't like wearing a wristwatch. 
The most basic pedometer in sports can be easily linked to WeChat. There is no problem of not updating the number of steps in use, and the number of steps the player wears with the wristband will be more than that of the mobile phone, and the ranking of the friends circle will also increase. In addition, there is a walking pattern (hyena mode) in which the arm is not swung and the trouser pocket and back are hand-held. The wristband can still be recorded, indicating that the triaxial acceleration sensor used by the wristband is still relatively accurate. 
In addition to the number of steps, the app terminal also displays the length of the walk, the distance, the heart rate (need to set the heart rate button to be normally open), and information such as energy consumption and resting time. 
Running data is the focus of my attention, you can manually open the app into the running mode or directly open for half a minute to automatically identify the bracelet, enter the running mode bracelet will have vibration and switch to the running interface, the bracelet will be automatically after the end of running Switch back to normal mode. 
However, if you do not open the mobile phone app, it will not show the GPS running circle diagram, only the step, energy, heart rate interface. 
Regarding distance calculations; 11 days of running in 14 days, the data recorded by bong3 is 122 kilometers. 
However, the average number of mobile app apps is 110 kilometers. It is estimated that because bong3 does not support GPS and network, the running distance is estimated. The algorithm varies from person to person and cannot be self-adjusted, so it is inaccurate. In addition to the feedback from customer service, this problem can only be calculated by myself. 
With respect to heart rate, the official stated that the bracelet uses a 24bit medical-grade heart rate chip. Looking at the blood oxygen index has been changing at 99% and 98% to give people an unclear feeling. Looking at the static heart rate again , the time taken by the wristband test is shorter, so the measured value is generally higher, and the contrasting sphygmomanometer is also shown to be high. It is estimated that the test posture is not standardized and the environment is unstable. But this does not represent the heart rate of exercise. Please continue to look down on this concern. 
Setting the heart rate to the normally open state gives a more accurate heart rate based on the average heart rate, and provides relevant information in walking, exercising, and sleeping states. 
The real-time heart rate is also based on the average heart rate of the running phase in the running mode, and then gives the average value when you lift the wrist display, so there will be no waiting screen for “measurement...†in the static heart rate measurement. accurate. (Long-term average heart rate is naturally much more accurate than short-term static heart rate). 
The app side can intuitively see the heart rate report of the year, month, and day . 
Addition; for the display of the running mode and the peacetime display is different, the running mode will only show the distance and heart rate two interfaces and will automatically switch without the wrist. (Small word is the current time and running time is not clear when the running is shaking ), so that when running, it is not necessary to do difficult gesture switching and wait for some irrelevant pages to directly understand the current state. In addition, the display is only clear to the kilometer. This can be seen clearly in the movement but the accuracy is as good as it is. 
In addition, each kilometer wristband in the running state will automatically vibrate to show the finished kilometers and the current pace. This is very useful for mastering your running speed (if you want to be able to display the step frequency, it will be even more perfect). At the time of 10,000 retries, it will also vibrate and display "Seizure of 10,000 steps" and running distance information. However, if the pace and running distance are inaccurate from the mobile phone, they need to be mentally adjusted. 
It was originally a function as a play, but one morning the hyena came back to sleep on the sofa and was recognized by the bracelet before it began to pay attention to it . 
Tests to remove the bracelet and sit for a long time (watching movies) will not be mistaken for sleep. 
Looking back at the sleep record in the app can show total sleep time, light sleep duration, wakefulness, average heart rate, and sleep report card. 
I said why the recent color is not good enough to find sleep quality is too slag by sleep analysis, and later to be improved as soon as possible. 
Look carefully at the screen, the effective area is not very large, but you can display two lines of information at the same time and scroll once (4 lines of content) 
The name of the incoming call can also be displayed, and the displayed content corresponds to the content displayed in the iphone information notification column. 
Unfamiliar calls can be viewed without a cell phone 
Because the vibration was too frequent, I turned off the WeChat and QQ information, and only retained SMS to receive important information such as bank reminders and verification codes. 
The way to cancel the vibration reminder is to shake the arm, so don't be surprised to see someone suddenly shaking the arm like a kitten, it may be rejecting junk calls. 
The wristband is set to turn on automatic heart rate monitoring, turn on incoming call reminders, turn on daily alarms, turn on all screen displays, gesture control, screen highlights, and text message reminders. 
The first time it was fully charged, there was 24% from the 3rd to the 15th. I thought that after two days of results, the power failure suddenly accelerated after two days. It can also be seen in the figure that the speed of power-off during the two days without running is correspondingly slowed down. 
However, according to the prolonged charging time and the late power-off acceleration, the performance of polymer lithium-ion batteries is not ideal. If they are not properly maintained, they may repeat the mistakes of bong2 short-lived batteries. Therefore, it is recommended not to over-discharge the wristband. It is better to start charging when the screen shows low battery (<20%). 
The fitness, cycling, and sedentary reminder functions were not tested during exercise. 
With my amount of exercise it should be easy to raise the pet and let it marry and have children... 
Unfortunately, after running, I often can't remember how to feed and I've starved to death... 
Comparing with Xiaomi 2, the performance of bong3's 60mAh polymer lithium-ion battery needs to be improved
