Answer to: Button missing from side (actuates functions)Hi, I had the same problem with my fitbit HR. I went on to the fitbit web site and emailed them asking to send me the part. They replied same day and said because my fitbit was 13 months old (1 month out of warranty) they would honour the warranty and send me a new one. I had to send them a photo of the old one with missing parts and I received the brand new one in the mail within a week. Great service from Fitbit! Couldn't fault them. (Note the replacement didnt include the dongle and the charger so don't throw those out & the replacement does not have any warranty but it is brand new).
