Optimum Series Automatic Smart Pump

...but wow! This is the best pumping striker over used!! Great suction!! Makes you cock feel rock hard! Had a ton of fun with this thing

Overall satisfied with the quality, it probably would have been a good idea for them provide some instructions on how to pump safely. Luckily there is alot of information online about the subject. I strongly suggest using the training function when starting off to prevent injury. Which is a nice feature that the pump has. The insert is very comfortable and its design would seem to make it very hard to accidentally suck your balls in( which is very painful). It is a good pump, which you can set back and let it work. Which makes it very easy to use and it is fun when you start seeing results

I have boughten over a dozen pumps and this one is the best one. The insert in it is something that I haven t seen or tried before so I had to try it. It is the insert and the power operation with the training is the best. The insert is amazing! It is so nice that insert gives your cock a cushion. It really hugs and holds it while the pump does it s thing. The training options are pretty awesome. You can literally just lay back watch tv and lube up, slide in, press power and choose which training exercise and then just lay back and enjoy . I would highly recommend this. Best one you can buy in my Personal opinion.

This is the best automatic pump I've used. The sleeve feels great while pumping and the auto features are great. I saw a difference in girth and length after the first use.
