First of all, I am way past the jelly stage. This thick and ribbed toy looked promising, yet when the feel of that jelly touched my flesh, I did a double take. Jelly like materials were only cool when I was just starting to experiment with toys. It's hard to clean, doesn't hold lubrication well, and as much as they'd like us to think, it doesn't feel real.

Aside from that, the thickness is just about average, enough to get that full feeling. The ribs are mildly pleasurable, if it weren't for the rubber-like material. The head of the toy was very well designed, "just like the real thing", and once again, would work great with another material.
The vibe was strong, with a turning dial gauge instead of a number system. Dial gauges are the way to go, if you ask me. The downfall of this part was the storage for the batteries is oddly designed, and hard to remove the batteries once they are in.
I say do the same thing with glass and forget the vibe, or try it in my new favorite the Velvet Touch material, and I could be very happy with it.
