worked as advertised, but for me the rings did not hold the erection. It is a bit uncomfortable, but would be worth it for those that can keep the erection. Pump certainly does the job.

I'm a diabetic and recently stopped responding to ED meds.My wife and I still are very sexual and this was something I had read about. I did not want to need a pump, felt stupid at first but I'll be dammed, the thing works and works good. It is really kind of weird at first but you get used to it... as is possible.

I have purchased several units prior to this one and this pump beats all the others hands down. Quality materials and functionality put it far ahead of the other I have tried. In my opinion, you can’t go wrong with the purchase of one of these devices.

Great E D pump. 100percent satisfied.

I've used other systems in the past but nothing compares to this product. The vacuum is incredible and the rings are superior to any other system I've had. I would highly recommend this system to everyone. Don't waist your money on a cheaper product, bite the bullet and get a system that's going to last and work like you expect it too!!!!
