Very basic, leaks badly, distorts badly
This is a very simple device--basically a hand-squeeze bulb on one end of a tube, with another bulb that inflates on the other. This was initially somewhat difficult to insert. You have to pump it up some to give it some degree of rigidity, but you're also giving it some extra girth....tho it IS just a thick balloon, so it can be manipulated. Lubrication is obviously important. Once you're in, it seems fine. Once you start inflating, it's not going to go anywhere because of the shape it takes as it inflates. It's "bigger on the inside", to paraphrase Dr. Who at the weirdest possible moment. Do be careful when inflating this. It might feel like you're just adding pressure, but you may also be causing trauma internally, from all the stretching, that can cause bleeding. The release valve works well, and the entire tubing can be quickly and (too-)easily removed from the inflated end. Which gets me to the biggest issue with this. The product page claims "better airtight, with special sealing performance", and asserts it has a "leak-proof design". These claims are NOT accurate, because while the unit IS airtight if you're not actually touching it once inflated, if you're actively using it, you are constantly battling leaks and a busting seal on the inflated end. If you end up pulling on the tubing anywhere near the inflated end, even slightly, the plug that's inserted into the inflated end loses its seal and air starts leaking out, deflating your good time. You don't have to do much at all, just moving the tubing at even the SLIGHTEST angle anywhere close to the plug, and it readily leaks air, and the plug often comes partially out, too. And so you're then you're forced to re-seat the plug while you're actively...involved. That sudden loss of pressure can also be jarring. It's REALLY annoying. The other very annoying thing is the inflating bulb end does not inflate evenly. It distorts, blowing out on one side, inflating wildly out of symmetry with the rest of the inflated end. Depending on where this side ends up on the inside, this can either be good or bad, either hitting the mark or missing it entirely. But there's no way to know or keep track. So that really sucks. I just wish this inflated evenly and symmetrically, all-around, in the first place. Alas, it does not. This is pretty inexpensive at around $10 at the time I ordered. I guess if you're looking for something cheap to get started, and are willing to put up with some--well, a lot of, imo--frustration, you could give this a shot. There are probably better units out there, tho, for the same or slightly more money, that wouldn't be so leak-prone and might actually inflate nicely to give you the effect that's one of the main reasons--if not THE main reason--you buy something like this in the first place. In the end, I honestly find it pretty hard to recommend. Read more
