I loved my Magic Band - I'd have one permanently attached to my arm if I could use it to unlock my house, get into work, pay for stuff, etc. I'm really good at forgetting stuff so it's pretty ideal for me.

We didn't have any issues using it to pay (and yes, they were definitely smart in making it making it so convenient...)
My husband and I went to Food & Wine this fall and I always had my ID with me - I was 32, but people always think I'm younger and I ALWAYS get carded at home so I felt pretty confident I'd need it for alcohol. I only got carded one time, though! Reading other people's experiences on here has me feeling like I must be starting to look old...
I would have liked to just have my band on my arm and my wallet in my pocket, but I always got stuck carrying a bag. We carried $1 Store rain ponchos, bottles for water (my husband honestly thinks the water from the drinking fountains tastes perfectly fine...), sunscreen, Advil, our phones, portable phone charger/cords, a camera, wet wipes, and napkins. We probably could've lived without most of that stuff, but it was nice to have.
