As stated in the other review, lube is a must for this one. But then again, all such toys should be used with lube, so no shock there.
I got this originally as an insert for a love doll to play with while the wife was out of commission for a while. It worked very well for that purpose.
It isn't very long, so to keep from popping out the end, use shallow strokes if you are of even average length. A closed end would be nice to stop this, but the open end means easier to clean, so...
The UR3 material is very soft, and they do include refreshing powder to restore it's silkiness when it starts to get sticky after the original powder washes/wears off.
Flip side of the softer material is that you have to be nice to this little pal when washing her. If stretched too far it can (and would) tear.
For the money it's a good toy, and if taken care of should last a long time.
Pros: texture, value, visually realistic, good for solo use or as an insert for some inflatable dolls.
Cons: length of the tunnel.
