They state that they have 24/7 technical support. I had a problem with the spray gun on a Saturday. Called for support and got a recording where I could select to hear about their 9 most common problems. Mine was not one of them and was then given the option for leaving a message and having someone call me the next business day. When I was called on Monday and complained, I was told we don't claim that it is LIVE 24/7suport. Then the resolution I was given was so crazy, it was not worth it. Bottom line, about half of the product ($350 or so worth) is now worthless.
