I do have a pump had it now for 21 years but I tried the stimulator did not work for me maybe lucky in 07 needed to have a pacemaker so if I had the stimulator they would have to remove it I can’t even use a tennis unit because of it. The pump is very good at what it does but there are things that go with having one a lot more surgery and don’t forget the refills every three months but it’s all been worth it . It made such a difference in my life just make sure that you have people that you trust with your life not trying to scare you off because I would do again even knowing everything that’s comes with it .
