I had mine inserted just last Setember....It's awesome. It takes awhile for your back to heal though. Like most Doc's they downplay the seriousness of the surgery. Make sure you give yourself time to heal. You won't be able to turn it up that strong and laying on your back and even sneezing makes it "jump" up higher. We call it my cattle prod @ my house. The thing also has a "remote". The HDTV references abound. I can tell youthis it has changed my life!
