this bracelet syncs with my Motorola phone just fine. The battery lasts a good 3 days. I noticed when walking on the treadmill it is best to wear it on my ankle. the accuracy of the miles walked is not as good when wearing on my wrist. It notifies me when i have phone calls, and also vibrates for alarms I have set on Zeroner. It tracks my sleep really well. Now I know exactly why I'm so tired in the mornings because I get my best sleep just before I have to wake up. some nights I wake up 8 times. (and I didn't even know it) It doesn't track my heart rate, but that's okay. the treadmill does.Things I wish it did: have the ability to post my progress on social media through the app. ( I can take a snap shot and post it but that's not the same), I wish the band was a little bigger or ability for extension for putting it on my ankle. all in all, for the price It's a good little tracker.

Bought this for my grand daughter as a first tracker. Works great as a first one and great price. She loves it. The app for it is not that great and since she doesn't have a cell phone I was hoping it would work on the computer like FitBit does...but it doesn't. So when I come to visit her once a week we check the app on my phone to see her progress. Its still worth the price for a first tracker.

The time works, and it's charged. But after the last charge it won't keep track of steps, calories distance etc. after the whole day of wearing it, it still says 0 for everything instead of counting.

The pedometer is either not working or my daughter's Fitbit isn't. I wore them both at the same time and mine registered 580 while hers showed 1864. Also, mine doesn't show who is calling or texting my cell like it did for the first few days. Thinking of returning it.

Great product for price. Love that it also vibrates when you get a text or call on your phone when used with the app.

Really enjoying this bit of technology. It was easy to set up and sync with my smart phone. The price point is excellent. I followed the directions that came with the device and in less than 35 minutes, I was up and running. It's comfortable on my wrist. Tracks exercise well. The sleep function is great and I learned a lot about how my sleep cycles work. It's nothing fancy, but I didn't expect a lot of bells and whistles. I liked it so much that after hearing me talking about how happy I am with mine, that my husband asked me to get one for him. His arrived yesterday and he was up and running within a half hour of opening his package.

I bought this product to keep track of my steps since I will be participating in a walking challenge; however, I don't believe it picks up all of my steps. I guess it's ok for an average.

SOOOOOO disappointed. I bought this for my daughter's 9th birthday and it quit holding a charge after a month. Went to try and exchange it and it is out of warranty, imagine that. What a piece of garbage! I guess I will have to invest the money towards a Nike fit bit. Don't waste your money.
