Some of you know that I was having a problem with my pedal control for my vest. Well I got tired of "fighting" with it & called the company. They were surprised I had no problems until now & are sending it overnight so I dont have to risk doing poor treatments longer then needed. I was so happy with them. I never had a problem from day one. Another note to......my paperwork from 1999 says American Biomedical Systems, but when I call the telephone number the company is called Hill Rom (sp). I remember someone talking about this company. I am assuming they bought out ABS or its a name change. I thought they were two actively seperate companies.
