Nike fuelband: The first generation only has black, and the second generation has added some color choices (black body with yellow, pink, red or black); The scoring system is still Nike's own refueling point system; This kind of bracelet requires high production technology and high defective rate, and the production factory does not accept external orders. The basic functions of this bracelet are as follows: the disadvantage is that it only supports ios and web, and does not support Android version; Splash water, but you can't swim or bathe with it; Didn't wake up painlessly. Ps: For me, the waterproof smart alarm clock is a fatal flaw, which is simply unbearable!
Fitbit flex: I've always liked Fitbit Flex: Fitbit Company in California was one of the first companies to develop digital pedometers. Since 2007, he has been engaged in the research and development of bracelets, so his step counting accuracy is relatively high. Flex is a dual system with led display, waterproof and support; The disadvantage is that there is no screen display time and the software does not support Chinese.
Fitbit Force: an enhanced version of Fitbit Flex, with oled display, which can display time, and its natural weight and volume are slightly larger than Flex. Flex has all the functions of force, plus a height sensor, which can track climbing stairs. It is said that the ios7 system (mobile phones above 4s) also supports caller ID. The disadvantage of this bracelet is that it is made of silicone, so it looks very old. Once you sweat or get wet, it is particularly uncomfortable to wear. In addition, it has a recognized fatal wound, and the button is very difficult to use!
Jawbone up 2:jawbone is a famous manufacturer of Bluetooth headsets and speakers. At present, it is also doing well in the bracelet. UP2 is charged by tpu rubber and usb, which has the longest battery life compared with the above models. Dual system, waterproof, with wake-up function; The disadvantage is that there is no screen and no data display; The appearance is regular and hard, and it is not very comfortable to wear.
12 1 bracelet (one, two, one): domestic, but cost-effective. This bracelet was launched by Shenzhen Bao Tong Power Technology Co., Ltd., and it is one of the first companies to develop digital pedometers in China. In recent years, research and development and production of smart bracelets have begun. The bracelet looks beautiful, with large oled touch screen, waterproof, compatible with ios and Android, sleep monitoring, smart alarm clock, social sharing and complete functions. However, the achilles heel of this bracelet is that its popularity does not match the cost performance of the product, and its promotion is not enough. Many potential customers may not even know it exists.
Glug bracelet: made in China, it is a bracelet jointly launched by Baidu and Glug. Jianghu people call it "jawbone". By combining the bracelet with Baidu Cloud, users can collect the data recorded in the bracelet to Baidu Cloud in real time and record it at any time. Underwater 1 meter waterproof, dual system, sleep monitoring, intelligent alarm clock. The price is much lower than that of several major American brands, and the function is OK. If you don't mind copying, you can consider starting, but personally don't like it, because you always feel that you have brought a copied jawbone.
That's all, once again emphasize personal views, welcome to correct me.
