I have a Fitbit charge 2, and both the original silicone band and another replacement band have caused awful rashes on my wrist after a few days of wear. In desperation, I found this band, hoping it might be different - Spoiler alert, IT WAS! I haven't had another rash, and the band is VERY comfortable to wear. Unlike other bands, it is easy to adjust perfectly for your wrist, and the magnet is very strong - no risk of falling off. Item came on time and packed well, and was very easy to attach on to the Fitbit. Highly recommend.
