I have purchased more than 11 fitbits over the past 3 years, and they have ended up dying with no apparent reason. I have been in contact with fitbit, and they have advised that there is not much they can do. I just bought one in january, and now it's dead. What a watch it is. I love the design, but it doesn't even last a year. In 2023, I changed about 6 watches until the warranty was finished. Spend a fortune on the watches. In my house, there are dead watches in every corner of the room, not working. What a watch! Now I have to put my phone on speaker, as I was so used to the watch reading my texts and more, but now it's dead.
