I don't think anyone in the group has one, but I'm curious as to your thoughts. I know a lot of people that have them and swear by them, and I absolutely love the features. My question is, for the more scientifically inclined peeps in the group: Do you think wearing something that gives off even a low-bandwidth signal (radio based wireless and low energy Bluetooth )most if not all of the day is safe? I want to think it is and can't find anything beyond random blogs that state it isn't safe. However, I have this nagging feeling that it isn't. While I realize it's nowhere near cellphone (or the dual monitors I use at work and at home for a good portion of the day) levels of energy being given off at a time, it just doesn't feel right. I was curious if anyone had any thoughts or insights?
