I have been using the BM x30 for a month and a half. Sometimes sometimes I have good suction and other times I don't. I have taken out the long insert and I get great suction. I prefer using the insert but it works better without it. I'm going to purchase the universal sleeve cuz of the gator bite. But I ordered the x30 cushion ring. Can I still use the cushion with the sleeve or it can only be used with the long insert?
