Selling a Tennis Tutor Model 4 Plus. It is in a 8/10 condition, I would say. It was bought in 2003, and only used 5 or 6 times for about 2 hours each, so that is the only wear it has. Battery seems good, I ran it for about 5 hours and it was still going strong, but I wasn't firing balls, just testing it. There is no remote, so that is the only thing that this machine lacks, otherwise it's the top of the line model. Wanting about $1100 for it... make an offer.
