It's very soft, and the design is extremely simple, so there is not much stimulation or feeling at all. Aside from bumps on two sides, and perpendicular wedges across the entire tunnel to the bumps, there is nothing to this design, and due to it's softness, you can't really feel it that much either. It can be a bit enjoyable if you use it slowly, but otherwise there isn't much enjoyment to be had from it.

It is pretty okay. It's quite soft, but a little firm and it isn't very stimulating because the internal structure kind of 'gives' a bit instead of pushing back as you use it. It feels more like a firm massage than anything wildly stimulating, which isn't bad at all, but it's not going to be something crazy.
The cover sleeve is okay, it's not a perfect fit on the toy (slightly larger) so you can use it with some other toys that have similar dimensions. I don't really use it though because it's an additional step when it comes to washing and cleaning. I don't really think this gimmick is enough to justify the higher price when the actual onahole itself isn't too special.
Can only really recommend if you just want to have the cover, otherwise look elsewhere for better holes.
