I love my Fitbit! This is a replacement for an Ionic I thought I lost. But, I found it and now my husband has one. I also teach aqua yoga and aqua aerobics and the Ionic keeps on working.

Watch is attractive - has the features I wanted
Rating: 5
When I plugged it in to charge - it started charging but half way through charging it stopped - it looked like it was dead and I almost returned it. I tried rebooting it by holding the Back button and lower button on the right side until it responded and that did the trick. The setup was simple and easy. The watch is now working without any issues.

Good watch
Rating: 4
Watch works great. I had one since 12/ 25/ 2018, unfortunately it stopped working in March of 2019. I purchased another one because it was so easy to use. I couldn't do without it. I love this watch!

WORST BIRTHDAY PRESENT EVER
Rating: 1
bought it for my husband's birthday, he's worn it the last 4 months, and twice it has died but it came back to use. It died 2 days ago and now it won't light up at all, not even hooked to charger. I have tried to contact fitbit warranty and Nothing.

Not built to last
Rating: 1
The screen fell off my Ionic a few months after it was out of warranty. I contacted Fitbit and was offered a 25% discount on a new device. Too expensive to fall apart!

Too good to be true
Rating: 1
There is a reason this Fitbit is drastically cheaper than anywhere else... it is a model made for Asian markets and possibly old stock. The battery on a full charge lasts 4-5 hours not the 7 days advertised by Fitbit. I have been working with Fitbit for weeks to get a new one with no luck. I will be returning it to Walmart.

I have been threw 3 fitbit ionic in 18 months do to the fact water has got inside of them. The company will not hold up there word on it about it can be used in the pool. waste of money if you are trying to track swim laps.

Defective Watch
Rating: 1
Received purchase quickly but watch is defective and will be returning. The watch does not turn on and packaging was not for a 'new' watch. We contacted Fitbit to confirm that there was nothing we could do to get the watch running. I recommend Fitbit but not from an unknown third party.
