I had two implanted in June 2011 (thoracic and cervical) and had a revision on the thoracic one 5 months later. They were a life saver for me, but unfortunately they didn't last long enough as I had issues develop and had them removed in January 2014. If I had to do it all over again, I would do the same thing. They helped so much in the time I had them.

When I had them I charged once per week. I never thought of it as a big commitment or hassle though. I just put the charging belt on while I watched tv and charged both units, one at a time. To me once a week is not bad. How long does it take to charge yours?

Why is it not working out for you? Does it not reach the affected areas well or what? Have you had it reprogrammed? I know mine took many programming sessions to get it right. I know that has to be frustrating for you.
