Ehh, not so great. [SEP] I dont know why it didn't occur to me that it would only come with one. I needed two for obvious reasons. So I will have to order another one to have a matching pair. But IDK that I will order another one, simply because I can not for the life of me turn the balls at the end to open and try this on. I have even enlisted the help of a few other people that can not twist them off either. I've never had this sort of trouble before. My next attempt will be will pliers but I think that's crazy to have to do. So right now this thing is pretty useless to me :(
