I work in an adult store and we got some new ones in claiming 'realistic', I din't recall the name rn, but Testing them by hand touch they felt really nice: moveable skin over the solidi body mimicking the erectile tissue. My only concern would be how long that moveable skin would last but I'm willing to try this weekend, so can let you know.
P. S. so, the ones we have in are a tad too small for my taste, but hell!
