Rated 2 out of 5 by from I bought this watch for my dad’a birthday. He was really happy that he receive text messages, calls, steps, etc just like apple watch for half the cost. But today the screen was cracked. He said that he only had it in his wrist. He didn’t drop it or hit it. So i called fitbit and they said that the screen fixing is not covered in the warranty. they can’t fix it at all and i get 25% off a new one. I don’t know if it will be worth buying a new one if it’s only going to last a couple of months.

Rated 3 out of 5 by from I'm receiving my 2nd replacement in 18 months While I like the functionality of the Blaze (although it's definitely bulkier than the apple watch) it KEEPS BREAKING! I have had to have one replaced (within the one year warranty) because it didn't hold a charge and they are sending me a second replacement (9 months later) because the screen keeps flashing. Not only have a I had to spend an hour with customer service each time, I'm without my device for 7 days.

Rated 5 out of 5 by from What I've Been Waiting For!! I LOVE this Fitbit. It does absolutely everything I wanted it to do. It's beautiful, easy to use, and very intuitive. I love the app, the tracking is quite sophisticated, and useful. I am exercising more every day; I'm just trainable enough that I love the encouraging messages and reminders, and reward reactions when you reach a goal! There's nothing like watching your wrist explode in fireworks when you hit your step goal! The activity data tracks smoothly with my Weight Watchers app, but the food data doesn't sync at all. I'm going to suggest to both WW and Fitbit that they work that out in the software. Highly recommend.

Rated 4 out of 5 by from Annoyed Gift-Giver I love my Fitbit and I bought it from Kohl’s a years ago so I wanted to buy one for a friend. Did it this Christmas and when my friend opened it, the watch had a giant scratch in it and had flakey skin cells on it as it had been pre-worn and returned. I was mortified. My friend of course was gracious and returned it for a brand new one at the store but I was so bummed that she couldn’t wear her watch right away. -annoyed gift-giver
