Well, this thread isn't exactly new, but I just discovered this section of the forum, so I'll throw my 2c in:
I bought a Flip Hole Silver for my significant other awhile ago.
- Very easy to clean. I LOVE that you can open it up to really scrub it down and properly air dry.
- From my research, the material that the Flip Hole is made of is much more body-safe and less bacteria-harboring than Fleshlight's. Frankly, Fleshlight's material is terrifying: highly porous, and it's difficult to clean inside them. I keep thinking I must be misunderstanding something given how popular they are, but I guess jelly toys are popular too despite being little UTI-generators. Also, male anatomy naturally resists UTIs far better than a woman's does, so if you're using it for solo play, perhaps it's not much of an issue. My SO and I, though, were looking for couple's play toys, so while it's of utmost importance that it's not hazardous to him, that's only half the battle: if he uses a bacteria-covered toy and we get frisky immediately afterwards, now I'm in trouble.
- Doesn't look like a sex toy. It looks odd enough that if someone were to see it, they'd probably ask what it is, though, and I can't think of anything you could plausibly pass it off as. If you or your SO find overtly sexualized toys offputting, this would be a great choice. Very sci-fi. It's really pretty inside, like it's fully of squishy crystals.
- At the end of the day, SO didn't really like it. He said it was nice, but he'd rather "use me", hehe, anyday. It wasn't uncomfortable, and it was good enough to get him off, but there just wasn't anything special or intense. So, it might be an acceptable option for solo play, but if you have a partner and you're looking for something to kick things up a notch, this may not do it for you. He far prefers the tenga eggs.
- It has limited uses (I think 50 is recommended). I've read that this may be more of a cultural thing, that in tenga's country of origin, people feel better about limited-use masturbators. (Sort of like how baking mixes weren't very well accepted until they started requiring an egg...human psychology has some weird quirks.) So, it might be safe to keep using it after that, or they may even come out with longer-use toys once Tenga is more comfortable in an international market. Still, after suffering the consequences of badly made, bacteria-ridden toys, I would never recommend that someone use a toy outside of the manufacturer's recommendation.
- Yes, it makes a lot of noise. It was a little giggle-inducing at first, but if you have no roommates and are pretty comfortable with each other, I didn't see that as a problem.
EDIT: One more note: The Flip Hole feels much cheaper in person than it looks on screen, the exterior made of lightweight plastic. I can't make up my mind if this impression is deceptive: the parts all fit together quite well, and there's no real reason that it ought to feel heavy. But, it scares me every time I put it back together, and we only used it 2-3 times: there's a plastic frame you have to slide onto it to keep the two halves of the toy together, and that frame just feels like it's going to snap someday. If it ever did, you could probably just use a rubber band to hold the two halves together, anyway.
Oh, and those "buttons" on the side: I couldn't figure out how those were supposed to work until I got the toy in person. They are not "buttons", and there are no electronics or moving parts in the toy: rather, it's a panel on the side that you can press with your fingers to squeeze the toy tighter around your, er, equipment. The rest of the toy's exterior is solid plastic, so without the panel, you wouldn't be able to squeeze.
EDIT #2: Take care with Tenga's lube. They gave us 3 free tubes, but we threw them all away: they contain parabens.
