I personally can't find anything bad to say about this. It has a really really strong vacuum. More than I was willing to feel and that is saying a lot. The pump is obviously super easy to use and the release button is very easy to find in the dark of needed. I think you leave this as is for as long as you can because some people my be complaining about another one of your toys you can spend time reengineering and making a little better but I think this is perfectly perfect exactly how it is. Please don't change anything. Jeremy

The basic design concept is good, the pump requires too much pressure to use for example using it as a clitoris pump works fairly well other than how much force you have to use. The quick release button is easy to locate and visible. I was impressed with the thickness of the material used at the entrance of the product.better than any I have used in the past. It stayed firmly on the cylinder and was not sucked inside the tube. The suction is adequate for beginners. The pump is very durable and constructed with quality in mind.

Relative to the electric pump its not as strong but easier to ease into suction, and you dont have to hassle with settings or charging. The seal cover is nicer and slightly thicker on this than the electric one although it only comes with one size. The air release didn't seem to work very quickly. Nice packaging and is what i've come to expect. packaging as usual. Showed up super fast. Was here before it even said shipped. If you dont might some work to get the level of comfort and it going slower than automatic ones then thisigjt work for you.

All in all , we love this product. We’ve used it twice already . My husband already is a very pleasurable size , but this definitely had me reaching for the walls! It gave him more length and girth and right after he experimented with it he was ready for fun time. It’s easy to use because the pumping is a bit slower manually, it’s easier to control due to this. If you’re looking for something with a vibe this is not for you as the only function is pumping . Now see ya ! I’m off to use this bad boy again!

Works great as it should

Works good and with ease. First use showed growth. Accessories are well made and durable. I'm interested to see the long term use effects.

Does the job you got it for.

This product made catastrophic differences in my penis size. It also gave me TOP of the line erections.

Good results for my husband!!

It works great
