CalExotics, Optimum Series Automatic Smart Pump Replacement Sleeve Male Silicone Masturbation Sleeve – 5 Inch Adult Male Masturbator Sex Toy – Clear Maintenance Free, 1 Count

Late update to a former bad review I gave to this product. I have since then used elastic hair ties around the rim and over the lip of the sleeve and they prevent the sleeve from being sucked into the cylinder. Works a treat.

Waste of money! There's no way to get even an average size penis into this thing, let alone one with any girth to it. Use with a pump makes it worse (even tried with various lubes & conditions of use). Once you become stuck in the opening, the interior of the sleeve collapses under the vacuum. I think that the concept is sound for such a device to be made/sold. But sadly, this “fail” is a poorly executed product by CalExotics. What's odd is that they are pretty consistent in typically making things oversized. How'd they create something so insanely tiny for such use!?! I'm truly disappointed in their marketing and quality control for not catching the design flaw. Perhaps they could have sold small medium and large (with this being their xxxtra small model). The only thing good I can say about this product relates to its construction. It is well made, and with quality materials. But unless you have a super skinny penis (not judging anything), I'd pass on this and save your money.

Great product! Feels great, made well fits the pump perfectly! Go ahead and just buy this you won't regret it.

Fits a pump well and can be used alone also.

Good

I purchased this for a comfort sleeve when pumping. Inadvertently used as a stroker for initial use/fitment, it’s a good feeling/sensation. Recommended as a stoker for those who perform in that manner.

good product

Very nice fit with a Paloqueth pump.The part that's designed to seal up with the inside of the pump tube seems to stay really sticky, though, so the whole thing has to be stored carefully when not in use. That part is not in contact with your skin at all, except when you're putting it in the pump. Still awkward & a little weird, so 4 stars.

Fits my Paloqueth pump, just be careful that it’s positioned right otherwise it can get sucked all the way to the top of the pump. Feels good, seems well made, hope it lasts.
