This type of thread is a headache. But, we had no issues with the actual magic bands. After 5 minutes we didn't even notice them because we read the direction and fitted them right. In fact they were so un-noticable that I forgot mine was on when we went through TSA at the airport. There are three camps for magic bands. The first is the "I don't want to wear it, they are tracking me, and they are telling me I need it" camp. The second is the camp that may actually have real issues with them. The third, could not care less.
We fall in the third. No carry a card or key, to the pool or anywhere else. They were always on our wrists except for bathing and sleeping. They are pretty darn light weight, soft and after a few minutes you forget about it. Can be used to pay for stuff with a tap while staying on property. They are not easily lost, although I have heard of people losing them now and then. The only complaint m wife had, was that she could not get purple.
