I have been a Fitbit customer for years and they really have gone downhill. I started with the Flex, then Charge 2, then Blaze and lastly the Charge 3.
All my issues have been with the Charge 3 that I purchased in December of 2018. In September of 2019 my Charge 3 lost it's mind and did the constant vibrating,etc. that has been discussed in this thread. I called support and since I was within my one year warranty they sent me a replacement.
My replacement started acting up today, 8 months after receiving it. Same issues. I was told by support they could not replace my Charge 3 since they base their warranty on the date of the original purchase; not the date of the replacement.
They offered me a 25% discount but only on certain items that I suspect they want to get rid of and you guessed it, the Charge 3 is one of them. I had considered upgrading to the Charge 4 in the hopes it didn't have the same issues as the Charge 3 but it's not offered.
As a side note, when I called support the phone rang once and then dead silence so I hung up and called again. Same deal, one ring and dead silence but a few seconds later someone answered. Also, their online chat doesn't work. You fill out all your information and submit and then receive a page that tells you they "have taken another path", whatever that is supposed to mean.
Fitbit support used to be excellent but not anymore.
