This sleeve will get sucked into the cylinder more easily than your penis will. The penis head initially will be pulled into the little entrance, but can go off center as the vacuum sucks in the sleeve seal unevenly around your shaft in the available space around your shaft. As your penis enlarges, the seal will tear apart and cause a vacuum leak as the little hole cannot stretch indefinitely. This product really can only be enjoyed by preteen boys with thin erect shafts not more than 1/2-in or 12mm. If your shaft gets 3/4-in or more in diameter, then it will tear. This is the second CalExotics brand item that has failed during initial use. I won't buy another product from them.

1st time experimenting with a pump. Add sounded good, When I tried to use it, it just sucked up in the pump tube. It is not useful as a seal. If you just wanted a hand toy, it is probably great, (Did not try it) but as pump seal it did not work for me.

It tears after three or four times. It should be made stronger against tearing. If this issue gets fixed, and price little lower, it's great.

Sleeve works great.. But... I used oil based lube with it..and it destroyed it. Split inside after 3 uses.. I should have known that soft compound isnt oil compatible...

INFERIOR QUALITY, LASTED MAYBE AN HOUR BEFORE IT STATED TO TEAR APART, NOTICED SMALL TEARS THAT GREW LARGER. DO NOT BUY THIS ITEM. WASTE OF MONEY!
