I've had the Fitbit Surge since Christmas, and had to give up wearing it after about a month due to contact dermatitis. I swapped wrists, took it off at night etc etc, and then stopped wearing it.
I contacted Fitbit a few days ago, and they're willing to give me a refund on it. However, I did find it really motivating, and would like to continue with another one.
Does anyone have any suggestions? Ironically, I have a metal watch with metal bracelet, and had it for years. Never had a problem.
