I have owned my PS2's a little over a year. I had the first ProScratch's for 3 years before that. They get used on average 2-3 times per week live a shows between 4-7 hrs. When I do weddings though, I will usually leave them off during the c0cktail and dinner hour to save some wear and tear on them, and just play either off my backup deck, or my PC for the c0cktail and dinner music.
