I bought a Fitbit blaze second hand and loved it, but three weeks later I began to develop skin irritation directly behind the casing and also where the buckle of the strap sat,
Took it off for a few months, not intentional I just forgot about it. I put it on today and the irritation is back only six hours later, exactly where it was previously. I'm amazed at how quickly it has escalated this time!
I am sensitive to some metals and tend to stick to platinum (which explains my distinct lack of jewellery) I just wondered if anyone else had experienced the same?
