The Flip Orb is accurately described above, but the erotic sensations deserve special mention. I found this to be highly arousing. The orbs running over the sweet spot on the head of my dick felt a lot like a good blowjob where the tongue flicks the head of my penis on each stroke. As noted above, the orbs flex and move and I found this to be very stimulating... almost too stimulating as I came sooner than I would have liked. As noted above, this provides a unique sensation, different from any sleeve without orbs or ribbed waves. Depending on how you hold it, sensation varies. The entrance hole is snug, and nicely simulated the sensation of a tight penetration. One word of caution. I put in too much lube and after I put my dick in it, a lot of lube gooshed out and made a bit of a mess. I used it alone and also with a partner - both were great but I think that I liked it more alone because it is easier to maximize sensation.
