Review: This item is perfect if your less fortunate to start with. - I don't understand why this thing isn't in the same product page as Size Matters Really ample penis. It's literally the same thing as that except it is black. Literally same exact product. On with the review. This thing last forever. I started buying these years ago. Probably like 7 years ago. And only have had three in that time span. They are beautiful lol. I'm pretty thick, and it give this thing more girth when I put it on. This thing alone is seriously the size of a soda can girth wise. I'm bigger than the overall length but that doesn't matter just gives it more length. The ball cuff stops that issue though. The material is soft so it doesn't hurt. The bumps on the inside really aren't for pleasure and shouldn't be described as such, as to it's more so to help the product grip so it doesn't move. Because it doesn't matter how big you are. When men get excited they start to leak and it lubes up the inside before you know it it's just as messy inside as out. Lol. My girl loves it. She can barely walk when I'm done with her alone. But with it. She describes it like almost blacking out lol. And she can't walk at all. Was my idea because I like more so pleasing than being pleased. I did well enough. But this really hitter go lmao. I recently bought this one for the first time. Out of the three that I have bought in the past seven years this is the first to be black. And I only bought it because it was a little cheaper. But it's literally identical other than the color. It's a great product. If your less fortunate to begin with. Make sure you check the dimensions..... dimensions..... dimensions.... dimensions. Because it is pretty big on the inside alone. If it doesn't fit it's worthless. You can be to big for it. But can't be to small for it.
Review: Big - I actually ended up using it once and throwing this away. From a mans perspective i would not recommend this product unless your significant other can really take a lot of girth. With some patience and lot of arousal we were able to use this for about 5 minutes, most of which was uncomfortable for my fiancé. if your getting this to add some size i recommend the smaller one, as this is probably way to much for 90% of woman.

### ⭐ Made with PVC. Don’t buy. Don’t use. Use only 100% silicone products.
*by C***. on February 10, 2020*

Do not buy and if you bought it, toss it. From what I’ve been reading, using these kinds of products made of PVC is bad for female health. I now don’t recommend any sexual aids that’s made with PVC. Chemicals in PVC products leach out into the body and is very harmful. Buy and use 100% silicone products only. Product is hard and uncomfortable for my wife and too small for me. Two times we tried to use it, we chucked it to the side after that and I’m glad we did. We’ve since thrown it into the trash after learning about the dangers of PVC sexual aids.
