I am 73 and have a Boston Scientific for CRPS in both legs and feet. I did my homework on different ones and decided on this because I can get an MRI if I required one. I have had several MRI's and had no problems with the implant other than when it needs recharged I get discomfort in my back. I went to a teaching hospital (UNC) for my assessment. Very clad I did that because of the options I received. I will tell you the rep I had with them initially was not any good. I did end up with another one in my hometown who was excellent and explained a lot more about how it functions to me. She also was able to adjust it to meet my needs. Customer Service at the Home office has been excellent when I've called. I have had mine for 4 years. When I get an episode with my CRPS I pull my remote out of my pocket and crank it up a pinch until the episode settles down. I do have to recharge my back about every two weeks. It takes about two hours each time. My remote gets charged maybe monthly and it's a matter of possibly an hour.
