this review title is: ehh not so great and the content is: i dont know why it did not 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 have never had this sort of trouble before my next attempt will be will pliers but i think that is crazy to have to do so right now this thing is pretty useless to me.there are other information for this review, one is this reviewer did purchase it and the other is 2 people think this review is helpful.
