I have had the odd thing happen where it disconnects while Im playing music. After unplugging and replugging the mouse it would start to work again, but this is VERY frustrating because I lost a lot of games because of this issue. the shoes are very nice but I would not recommended if they break this easy . I have even worn them under my Mardi Gras gowns (yes not stilettos) who cares when u are there to have fun and dance and no one sees your shoes ??. Arrived super fast, yay! Also fine with smaller ones. These pictures were taken on June 1st and theyve had these pairs since early January, each pair washed at least once, if that gives you a sense of how they hold up! In short, the automatic switching of devices works very well. However, when it arrived, it was damaged. i tried to heat them up with hair drier before removal but the effect was pretty much the same as without heating.
