Terrible quality after wearing this for a few months -The base where your foot rests started peeling away revealing a black blue substance that now stains my feet that color every time I wear this slipper- it was fantastic in the beginning but clearly it is all window dressing and underneath the footwear is of absolutely pathetic quality I have no complaints. Considering getting another one for my wife to use. In fact, he is a very large person, and buying anything is tricky. Adjusts great. This is a excellent speaker if youre having friends, family, relatives, etc over & youre in a medium sized room (such as the living room). Lot of times I am thinking there must be some more instruments than this speaker is reproducing. Feel strong and sturdy. Per il resto ottimo. Thick and functional.
