I am very disappointed with these machines. I have had mine in operation for 16 months and have a lot of problems. I bought 5 and every one has had problems. I have had to replace keypads, coin mechanisms, home switches...and these machines do not get an inordinate amount of use. I hate calling tech support...smart, but absolutely no people skills. Should not deal with the public!!
