Review on Smartbracelet 1 1 Inch Display•Animated Swimming Waterproof by Keith Harris

There are no instructions on how to use this bracelet, just a brief overview of how to charge it. Do developers really think we're all born with an innate knowledge of how to use all the features of this thing? Very frustrating. I did a 16 mile bike ride after launching the bike app on my phone. I assumed that the bracelet would track the journey as it must have a GPS function. But when I got back to my car, I hit end on the app and it only showed 0.02 miles. Does this mean I have to take my phone with me when cycling to track it? If so, I could just use Google Fit. Also, it hasn't told the app anything about my heart rate since the first day I turned it on. If I don't get an answer from the seller in the next few days, it will be returned. It's an attractive build and looks like it might show some wear and tear, but the poor connectivity and particularly the lack of any instructions make me give it one star.
