I bought my Charge 3 January 31st, 2019. This is important because the Fitbit warranty covers a year from the purchase date, and because at that time, the Charge 3 cost what a Charge 4 does now.I absolutely love my Fitbit’s functions. It has been very helpful to me in getting active and losing weight. I’ve always had issues wearing watches or bracelets on my wrist, but I never had that issue with my Fitbit. I’m not sure if it’s because of the strap or the lightness and shape of the Fitbit, but it hasn’t been an issue to wear it through the night. I even bought an Aria scale because I was enjoying it so much.The app is mediocre and a lot is locked behind a premium service. Fine, I get it. It’s a little silly that you drop so much money on a device and then have to additionally pay a subscription if you want to access all the features, but that’s how things are now. And the basic data is fine. It’s just nothing to write home about. For example, if you want specific data about your heart rate while you sleep or if you want to enroll in any of their “wellness” courses, you need the premium membership.I’ve had issues on and off where the device says it’s at full charge (after I charged it shortly prior), and then a couple hours later drops dead. When I plug it in again, it says it had no battery left. So I’d wait for it to charge again, and it would be back to its normal 5-6 days of life. This happened maybe 3 or 4 times in the year and nearly 4 months I’ve owned the device. Annoying, but not a deal breaker.The band of the Fitbit also broke within a few months of me owning it. And I’m not super rigorous with it’s use. I wear it on my wrist and don’t do anything too crazy. I haven’t even gone for a swim with it, despite its compatibility. That had me a little displeased, but I bought a 3rd party replacement (it was 1/4 of the cost of the one offered by Fitbit and I figured if this was going to be common I didn’t want to toss my money down the drain). Funnily enough, I haven’t had any issues with the band even LOOKING like it was going to break since.Then came the straw that broke the camel’s back. One day, (May 9th), I plugged my Fitbit in to charge like normal. As soon as I did, the screen corrupted like you can see in the picture. Googling the issue told me that this was a fairly common issue, and I tried all the troubleshooting offered with no luck. Not only is it corrupted, the sensitivity of the screen has dropped drastically and I have a hard time getting to the swipe menus. Sometimes, it turns completely unresponsive for a short period of time and I have to hit the button until it does. This is where that year-long warranty comes into play. It had been a year and about 3 months when this issue occurred, and I emailed Fitbit in case they might have a solution. Alas, after waiting over a week for the first reply, they gave me a troubleshooting solution I had told them in my original email that I had tried with no success. I emailed back and told them that. They replied about processing a replacement, asking where I live and where I bought it. I replied, and then they asked me all the way to my detailed address, phone number, and yet another picture of my Fitbit so they could see what color it was to send. I was obviously happy since I knew it was technically past the warranty date, but since they hadn’t seen an issue with my location or where I purchased it, I figured it was ok. I mean, it’s a little disappointing to have an expensive device falling apart after a bit over a year of use. After that reply, there was nothing until today (about 5 days) when I finally get the reply that it isn’t eligible for the warranty. It took nearly two and a half weeks for that conclusion! I understand it being behind the warranty, but I’m left feeling frustrated by the mixed messages and the quality of this expensive product, especially because I did not do anything unusual to break it.Tldr; It has nice functions, but you’re better off going with a different brand that has better quality.
