The only way you could go wrong with this product is if you're very large.
"First of all, the hole is fairly small and tight. But, the material is very stretchy. I'd consider myself a little under average in terms of girth, but I can't fit inside without some lube. I wouldn't even want to try since the material is very soft, squishy and clingy.
Make sure the lube is water-based and not oil-based. I went ahead and bought the recommended 8oz. bottle of "Lube Life" here on Amazon and it works great. If used smartly, you only need 2 or 3 good sized drops of the lube to get the job done.
As for what I don't like about it, there are two things;
1. The ring holes for your fingers. This one is more of a nitpick than anything else. They serve no functional purpose and it kind of just gets in the way of you and your satisfaction. I'm putting thought into just cutting off the top half of the rings so that the grip serves the same purpose without having to mess around with getting my fingers through the rings. I know it sounds stupid, but the material is clingy and stretchy and it's not as simple as just sliding your fingers through.
2. If you don't mind getting your gunk on yourself and then cleaning it off, this isn't a problem at all. But, I prefer to try and shoot into something and there's a lip on the exit-end of the device that all but guarantees it's going to catch a little bit of the mess and sometimes gets it into the product. That being said, it should be cleaned after every use anyway and it's very easy to clean.
The product is made of a very squishy material that I feel might end up tearing a bit if a person gets a little too rough or overzealous with it. I've only used it a few times, but I've noticed a few... what I can only call "stretch marks", around the exterior and interior of the product. I'm not sure if they were there when I got the product or if it's caused from use. Either way, the thing seems fairly durable, so it's hard to believe it's got stretch marks from use already.
I'd recommend keeping the box and bag it comes in, as the product itself is very sticky/clingy and storing it could present a problem. I like to just take the bag, lay it flat and roll the product up in it. Then I'll just place it into the box. Otherwise, the product clings to damn near everything and putting it back into the box or into the bag it comes in would be too much trouble to go through every time."
Absolutely a warm, wet, tight slurping pleasure to use.
"Was super pleasantly surprised at how good this toy felt, it slipped right onto me with such ease and slid even easier. Needed not even much lube to work into a nice rhythm and the little finger holes keep it tightly wrapped around me at all times. The sounds are also nice and erotic too. It's a perfect addition to my collection and the price is even better for something that feels this good."
