Got this for my man and he loves it has good suction and it does miracles especially when it’s needed. Get your man one and you will never regret it
I told myself I wasn’t buying this again… and here I am on my second one. That alone says everything. This thing does exactly what it’s supposed to do, and it does it way better than I expected. The design feels solid, it’s easy to use, and the experience is intense in the best way. Definitely one of those purchases you try to act like you don’t need until you realize nothing else is hitting the same. If you’re on the fence, quit playing and just get it. Five stars easy.
This Masturbator is incredible and I couldn’t be more impressed with the quality and performance from the pump !! Guys this pump has got exactly what you have been looking for!! The suction and its deep rumbly vibration mode is matchless! This baby thumps and sucks it so powerful, it’s insane! Get this penis pump and discover exactly what that big D needs !! Not to mention the banging joyhub app and all its killer ai girlfriend fun you’re gonna soon have too!!

High quality product. Reasonably well priced, though a bit up there. Once it's on, it's hard to get off, but I like that personally as the seal holds quite well. Comes with lube, which is nice, and the app is very good for controlling it. The vibrations feel nice too.Only major downside is the thing is HUGE, like the size of my arm. I never really realized how big it was when I bought it - it's not exactly easy to hide. Despite that, still a decent buy.
