This is a great ADD ON to any vibe. I find this attachment to be one of the best due to it's EARS.. They move all around your clit with a little lube. If your not using lube the ears tend to stay in one place. I perfer the lube so it will move around more like oral sex does. It's a STURDY SLEEVE and keeps it's shape with out splitting or cracking. Cleans up very nice with soap & water. I will be ordering at least 3 more..WORTH THE MONEY GIRLS!!! Buy 1 and put it on your favorite vibe and you will see..
