This isn?t worth spending the money on! There is no place for the hooks to hold on to. But even with a shelf missing it?s still very stable. Item is very light in weight? Not used to date so dont know how sturdy. Slippers are very comfortable, look nice, non slip, perfect fit, and are warm for our cold Canadian winter. If there was 10 stars this product would get it! The sound quality is good and the volume is adequate for my hearing but because the ear pads wont fit over my ears theyre hard to wear for more than about a half hour to forty five minutes. received it new. the extra screws and the extender.
