Very sturdy and well built. This was like Goldilocks finding one that was just right. The design of all of the pieces fit with a contemporary bathroom in that they are simple. These were a gift for my husband and although the top portion had a nice quality to them, the sole was very rigid and completely counter to being snuggly and comfortable which you would expect in a slipper. a cheap stick can accomplish the same task too. I just received them yesterday. I figured there had to be a better way so I found these. I use these to listen to audiobooks and music. Not sure why I was asked to rate ?suction power. Anyway, im sending these back tomorrow.
