ehh not so great [SEP] 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
