Charges relatively fast too. Theyre very comfortable! We both are able to find a comfortable setting on the adjustable seat. Its so stupid how bad this works because remember, theres a big sound leak issue which SUBsequently leaks all of the low frequencies. It also is very clear that anyone with this device is actually wearing such a device and possibly talking on it. The first three pics show how they fell apart within five months: toe stitching falling out, leather lace broken, fur not just matted but fallen out, and (not pictured) the plastic insert that makes the back of the heel rigid broke and pieces of sharp plastic stuck out into the slipper. I did receive 2 different sized shoes. The heel is much thinner & there is no arch support. If they do so, I will update my review to reflect the excellent quality of Plantonics/Polys product. Theyre waterproof and they clean easily.
