The only way to go
Great tracker. Ive been using Fitbit for years. Just get the insurance.

Worth the price
The products is okay for the price. Battery doesnt last as long as it says. It's not scratch proof like it says so be careful. All the options are nice. Sometimes it has a problem connecting to the phone but if you reboot it it normally reconnects. Overall I like my fitbit. I had the firbit alta and it died on me so this was the watch that I choose to replace it. I also like the fact that its waterproof though.

Works well but not for long with manual labor
First off I love my fitbit charge 4 and i have used them when they came out. It works well, however there is something that needs improvement. I'm on my second pair and probably last. It had just broke the same way as the first one. I work as a mechanic and im constantly put my arms into though and tight spots and so i like the low profile of the watch. My problem is with the bracket on the watch itself and that it screws into plastic mounts. both pairs have broken at that plastic mount and theres no way to fix it without replacing the whole bottom and at that point you may as well replace it. Again I love the fitbits but this is a common problem for me and i will probably look for a different watch. If this problem is resolved or if its not a problem on the newer one i will come back.
