Review title is Didn’t fit [SEP] I was really excited to have this back brush. But when I went to put it together it didn’t go... no matter how hard I tried! That was upsetting. I had to get my dremel out to sand it down so it fit better and it’s still not all the way on. With that said, the brush is super nice and scratchy on the back. And the foot brush/pumice stone is really nice too! I hope your brush combo has less flaws.
