I had a bubble form on my watch band and I believe this is the 4th replacement. Because they don't have any Vivosmart 4 left in stock they refuse to exchange it. The last time they sent me a replacement I asked the rep, "what happens when you stop making this watch" and he replied that "they redesigned it so the battery bubble won't form." They offered a %30 discount on a new watch but that just doesn't seem logical.
The bubble finally burst and I noticed because I felt a burning on my wrist. Does anyone have any suggestions on how toxic the liquid is? Or suggestions on other brands? I like the small design of this but If anyone has experience with fitbit let me know. This whole experience has been frustrating.
