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

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.

Exactly what i was waiting for
Rating: 5
i owned galaxy watch and i loved it except it was little too heavy. also, i do not like fitness type watches, so i was literally waiting for watch3. super light, works well with bixby, samsung pay, and a lot of customization you can do. i always wear watch to track my sleep, and it didnt bother me at all. at last, watch trade-in was really good promotion!

Familiar but lighter
Rating: 5
i'm happy with this. it's the best upgrade from my gear s3 frontier. feels the same but lighter in weight. only drawback is the strap cause it felt a bit cheap. i got myself a silicone strap for it later on.

Perfect
Rating: 5
i got this as a replacement for the 41mm size, which was too small. the bezel on the 45mm actually seems shorter than in the 41mm! it's easy to use (both the bezel and the touch screen). the battery life is superb. the screen is beautiful. and since i had a trade in (active 2 - no bezel - good riddance), the price was great, too.

Gr8 watch, superb gizmo,fitness kit not 4 every1
Rating: 5
this is as beautiful and functional watch, phone, info pod, music player, gadget, companion and alarm as you could want, worth every cent. the learning curve is minimal if you can find your way around a smartphone. but the fitness stuff, which is touted as the centerpiece of this timepiece's acumen is just for gym rats or runners and such. i garden, walk dogs, putter around the house, dance now and then and the watch's workout detection for my everyday regimen is quite confused and almost useless. for everything else it does, and there's a lot of it and the sheer snazz of it, i love it. i'd give it a 4.7 but you can only rate in whole numbers.

Great integration with smartphone
Rating: 5
this watch seamlessly integrates with my s20 ultra and i love how i can receive notifications from all my apps on the watch. i get about 2 days worth of battery life with normal use and the always-on display turned off. best surprise so far is being able to connect to my ultra's camera and see it on my watch face and take pictures!

Great watch - so so battery life.
Rating: 4
Upgraded to the Galaxy Watch 3 from the original Galaxy Watch. Love the larger screen. Love that it's slightly slimmer. Love the new sensors, including Blood Pressure Monitoring (Not officially activated in the US yet, but there are workarounds available). Only complaint is that I'm not thrilled with the battery life. Still easily get a full days worth of use even with sleep tracking, but nowhere near the life compared to the Original Galaxy Watch which could push 3 days.

Best looking watch on the market.
Rating: 3
the design is flawless and the rotating bezel is infinitely better then the touch one on the active 2. i am used to the subpar battery life when compared to let's say a versa 2, so i don't really fault it much because the tech and os is muchhhh better then fitbit. i can't excuse away the slow charging however. it is brutally slow and for this amount of money it is inexcusable.

Just Ok
Rating: 3
i regret upgrading from the galaxy watch as there is nothing worth the expense for this watch. the extra stuff they mentioned like the workout, sleep, etc., not that great. the other watch i had was better in doing my every hour stretch reminder this one is weird, it's a hit or miss. the few things i love about this watch are the lightness and also the look on the screen. bigger and aesthetically more pleasing. battery is fine as well, get two days or so. i don't think it is worth it and when i trade in i realized i should have kept my watch.

Original still better. Not worth hefty price tag. Key features not enabled. Walmart customer service is the worst!!!

Disappointing new design and Wear App
Rating: 1
the protruding watch buttons on the right side is poor design if you want to wear the watch for road biking and during circuit training with weights and especially push-up. my s3 is much better with recessed buttons. i am returning it until they learn to get feedback from actual athletic customers. also, what's wrong with their app design, why does it have to combine the watch and phone steps? i want to be able to just use the phone or watch, not the cumulative, which could be double sometimes or 70% to 30% and the 30% is probably already in the 70% of the number shown. makes no sense at all, separate them out. don't buy this if you are going to use if for active life, go with fitbit or some other device
