ZEERKEER Fitness Tracker,Smart Bracelet with Color Screen Activity Tracker Watch ,IP67 Waterproof Smart Band Calorie Counter Pedometer for Men, Women and Kids

The idea of it was great, purchased because of the EKG ability, but was never able to figure out how to actually get the reading. Only got one after pressing every button I could find on both the iPhone App and the watch. Unexpectedly, I found the sleep tracking the most interesting. Not sure I trust the readings, though, and many evenings I had the watch on but it did not record. Regardless, a few days ago a black spot began covering the entire screen, and now it won't charge either. Totally broken. Feel like such a sucker! Although it doesn't have EKG, I suppose I'll just get a tried and true Fitbit.UPDATE: So, the black spots went away so now I can see the screen. However, it only sporadically tracks my sleep. Maybe half the time. Not good enough. Should have purchased a tried and true brand for the price.

I work (usually) 50-70 hours a week. Many of my shifts are overnight. I had a fitbit to track my sleep for a few years until it cracked and my husband bought me this. What garbage! It will ONLY track sleep AT NIGHT. Nighttime is THE ONLY time it will allow for you to sleep. The attached picture shows that I only got 1 hour and 43 minutes of sleep between 1:36 in the morning at 7:12 in the morning. Well...my shift last night BEGAN at 10:00pm and lasted until 6:00 THIS MORNING!!! AND, NO, I DO NOT SLEEP AT WORK!!!! I actually did not fall asleep until close to 10 this morning and slept until around 4 this afternoon. My fitbit would have tracked that. This clearly does not. Returning.

Not the color I wanted. It is more pink than purple. Haven't had a chance to use it yet. going to have to exchange it for another one.

This didn’t work at all and was very difficult to return as it had to be shipped to China.

Good: price, long lasting battery, comfortable.Not so good: can not see display in daylight, pedometer is affected by riding motorcycle or lawn mower.

Looks and feels comfortable to wear BUT it’s a pain in the butt to work. For any readings you really have to play with it. Directions come in very poorly written English and the app is the same disappointing way.

This fitness watch is highly accurate for heart rate and blood pressure! Haven't tested the ekg function yet.
