    Excellent. Small battery...

    Fast shipping. Tested. Very satisfied. Amazing product!

    Wristband is working and shows charging, networks and accelerator info. Didn't yet tried to reprogram it. The IMU chip is different, than in description - LSM9DS1 instead of the MPU9250, so could be a bit cheaper. The only option available is medium battery, but I would prefer to have bigger battery or vibration motor included. The option with heart rate sensor or sensor separately would be nice as well

    item like descrition, works good, but a little bit difficult to program with ARDUINO IDE because different cores of ESP and ADAFRUITs display libraries. no impressive documentation in my oppinion.

    Nice little programmable device, but the battery life is disappointing. To make it useable you need to use every power saving trick in the book: minimize use of WiFi and Bluetooth, use sleep mode as often as possible, dim the display. Banggood delivery very swift!

    Nice product, almost as described. The description in the linked respository are clear and easy to follow. I recieved a (newer!) version of the band with the LSM9DS1 instead of the MPU9250 that's mentioned in the description.

    Reallly enjoyed this wristband. As has been mentioned, the battery life is very limiting, but with a very basic 'wristwatch' Arduino sketch I can get 18H battery life from it! Been impressed with the build quality and reliability so far!

    It is a nice developer tool. Do not expect long operational time from that tiny battery but for developers it is a nice gadget. If you have some experience with ESP32 you can make your own program for it quickly. (eg. home automation)

    A bit on the "cheap" side, cannot clip it back on properly after being opened only twice. It does work however, and is a nice project. I still recommend this product, but be sure to check the new version, it is not much more expansive, but looks quite a bit better

    Unfortunately it broke already due to pressing the screen to push the esp in the case. i like the product though battery time is tricky!
