Qualified review, I have not tried this with a partner yet, just received. Tried it on, its built well but let it be known there is very little stretch in the "harder" rubber construction of this toy. If your a larger diameter person this, once on, can be a bit constricting and tight (I test fit them all for usability). It wraps a good amount of the penis shaft and stands off the body a little bit. The ring around the balls is thin and round, moderate but OK. I'll repost after trying with a partner.
