I worked at the ink life tour this weekend and the guy who invented it was across from me..so I walked over to play with it..he had some half dressed chicks trying to tell me about it...it uses ttech cartridge and it is kind of clunky..I wasn't impressed at all..they tried to tell me it is the first ever machine of its kind..I said well I think the stylus took that spot. any how just thought I would share
