I think the biggest other concern I had was the "clickyness" of the left and right mouse buttons. Im impressed. I needed a pair of sandals with a back for work and I liked the removable foot bed and look of these. Then with my neighbor needing masks to be safe at the hospital. The right side A button was surprisingly natural feeling because my thumb naturally rests on the right A button instead of the bottom button like the xbox layout that Im used to. Already got a longer charge cord and adapter which I can use elsewhere if I do send these back. I think this might be my first amazon review. The slippers are very comfy, though, well-cushioned and warm without making my feet too hot. Considering the price, overall, it is a good purchase. Eigentlich bin ich ein überzeugter Birkenstock Fan.
