CUBOT Fitness Watch for Men with 25-Day Long Battery Life, Rugged Waterproof Smart Watch for Android iOS Phones Support Blood Oxygen, Heart Rate, Sleep Monitor, 13 Sports Modes, Step Counter

I love this watch and it works very well. My only complaint is that there is no timer app, only a stop watch. That is pretty essential for fitness to have a simple timer (and stopwatch).

This watch worked 30 days and quit. Do not buy it. I tried contacting customer support. They asked for a video of it not working. Still no new watch. Stay away unless you want to waste money.

I've been using the watch for a month to do pool laps about 3-4 times a week. The watch does not track swimming as an exercise (my bad for not checking more closely the watch description). Anyways, I was really looking for something that will give me the time and a crono while I'm swimming. I didn't expect to use the fitness applications, but still go it as a "why not" given the price. The watch is indeed water resistant and I have only charged it once in a month. What drove my crazy is that the watch takes the swim strokes as "input"; that is, the crono stops or go without my input. Worst, even the face of the watch changes while I'm doing strokes (and I technically know how to swim), sometimes leaving me with a face that I cannot read on the water (I use glasses). Waste of money for me.

I liked this watch until it stopped working in two months
