[Paul] Have you gone to their web site?? If not do, they will send you a free video. I don't have one but my father-in-law does and once he got it ajusted he likes it. Also, I have read more on people that swear by it than swear at it. If you can find a used one you will save some bucks that way, otherwise a bit pricey, but than again more likes than dislikes. JMHO, Paul
