Conclusion
This is a very good penis pump. It is great for exploration and learning of the effects of penis pumps. I only wish the instructions covered more of the modes and a small troubleshooting section. For the troubleshooting section I wish they would include failure to get a seal and failure to maintain a seal. When I first began using this product, I was unshaven and the pubic hair caused the seal to not be maintained. After I shaved my pubic region, a seal was easily maintained with very little lube, providing with the correct experience from a penis. I did not like having to explore the modes without any knowledge because if I found one that I didn’t want to try it was already too late at that point.
