I reviewed this one earlier: the sleeve works well for me, so much that I ordered a backup should something happen to the first one
Tried one of the replacement basic, and the suck & stroke masturbator replacement stoker sleeves. This Optimum Series is way better by far. Inside diameter is generous enough (for an average size guy) to allow pump vacuum to work as designed and move blood into the penis, yet still allow contact with the inside texture beads.
As a younger man I would purchase these items for novelty. Now that I’m over 50, and experiencing “the change”. I’ve found that they help the situation. The sleeve was very comfortable and I actually was able to stroke and feel the texture against my penis. Would definitely recommend!
This is far tighter than the mouth sleeve, which is really nice. Also, it's better designed to handle the "stress", more reinforced, than the mouth sleeve. Really like the feel, don't like the indentations from the nubs, but the nubs feel really good, LOL
sleeve is broken.... where can i buy replacement?
