Would it not be possible to make sleeves that provide both a vacuum seal and additional sliding stimulation? The X-Tight Vacuum Seal simply isn’t very good and doesn’t work well. Wouldn’t it be possible to integrate features like that directly into the sleeve design, while also providing a really smooth in-and-out sliding function?
That’s why I was thinking of something like a fin structure or in-slide ringstructures. Also, the sleeves for the medium unit could have narrower versions as well. It would also be helpful to include the dimensions, as is already done with the latex sleeves.
Unfortunately, the fleshlight units are too heavy. As a result, there is virtually no sliding movement noticeable anymore. the sleeves from ultra are not good enough. Onaholes would be better, but no airsleeves available. This also highlights the problem of the Vacuglide seems to be too weak for heavier use.
Seems finding the right sleeve material, is the units biggest problem - not?
the Vacuglide Clear Glide Rail Sleeve, I found this one quite disappointing, to be honest. I expected more of that kind of structure. But this one seems more suitable for units that make rotational movements.
In any case, there’s still something missing in terms of structures at the beginning of the sleeves, to make the gliding movements even more enjoyable.
Hopefully, this is useful information to keep in mind for future improvements.
