We've tried several extenders

We have tried several sleeves, but this has received the most positive response from my wife, and therefore from me. Firstly, the feel is excellent, very soft and stretchy, and there is no off-putting smell. Putting on the sleeve is easy, but you really have to be erect first. A small application of lube helps to get you in, but you don’t need lots. Just open the product slightly, and you can slide in quite easily. Unlike some other sleeves that have scrotal holders, the stretchy material is extremely easy to get round your balls, yet still feels very secure. Also because the sleeve is slightly see-through it sort of blends in with your natural skin colour. Once you're in, just apply plenty of lube and you're ready to go. Also the sight of seeing myself, just that bit larger entering my wife, was extremely erotic. The response from my wife was extremely enthusiastic. She really enjoyed the extra girth and the orgasm it brought on, yet said the size was much more manageable than some of the other larger and more rigid sleeves we have tried. This is an excellent sleeve, which adds girth, but not really length. It feels great for both, is comfortable and easy to use. Highly recommended.

5 stars! A+ for starters! Great product and fast shipping. The size, the fit, the feel: all perfect and just what I was looking for in a soft, comfortable sheath. Now, if we could something like this in! Excellent job folks!

A Good Value

What He says: It's not super easy to slide into unless you are very lubed, but it's so stretchy that you can also just flip it inside out and roll it on. I'm the max recommended length for this model (just a hair over 6"). When I put it on, it does not reach all the way to my base, however the ball loop is comfortable and when you thrust, it will stretch to the base as needed. Due to the internal textures and extra tightness from my partner, i find that this makes me more sensitive than if i were using a condom. Note that this is not meant to be a condom replacement, so use discretion. It also makes for a pretty strong masturbation sleeve What she says: it doesn't feel natural, but it is her favorite toy thus far. It adds padding, which makes intercourse more comfortable. If your partner wants something that is super solid, i would look elsewhere. Even when completely filling the sleeve, the exterior remains slightly squishy. It's easy to use but might take a couple times to get it on quickly and it's easy to wash, which means I'll never hesitate to break it out if the desire arises.

I love, she loves it

I love it! She loves it! Gives me some extra girth which she obviously enjoys. So easy to put on compared to other sleeves. The main thing we use it for, however, is a male masturbator. For me, it is the best I have ever tried, including fleshlights and tenga. This thing feels amazing! Get one just for that alone.

Fat Boy

With lots of lube, inside and out it is great for both. Also great feeling solo. Super soft feeling. Hope it lasts a long time.
