The only way to go
Great tracker. Ive been using Fitbit for years. Just get the insurance.
Verified Purchase
Worth the price
The products is okay for the price. Battery doesnt last as long as it says. It's not scratch proof like it says so be careful. All the options are nice. Sometimes it has a problem connecting to the phone but if you reboot it it normally reconnects. Overall I like my fitbit. I had the firbit alta and it died on me so this was the watch that I choose to replace it. I also like the fact that its waterproof though.
Verified Purchase
When I opened the box, it was torn on the inside, a returned model. Very hard to work, had to YouTube everything to figure out how to work the watch. But now I've got it going and recharging and hopefully it will last. Don't like buying something new and getting somebody else's RETURN !!!!!
