I have had so many problems with my 2 Tuff machines that I would never buy another one. Customer service sucks too from Spraymart. In fact I currently am using a 3rd Tuff unit from a friend while my other one is being repaired. My main problem is electrical & the charging systems. Tuff runs the ground wire from the battery to the sheet metal screw holding down the water tank on the frame. Eventually the corrosion from the water tank will cause a poor ground leading to other problems. I had a ground wire welded right onto the frame of the machine. Even the machine I borrowed ( 10 months new) is having problems also. In my personal opinion I would go another route as far as machines are concerned. I now run 2 batteries on my machines as well as installed a 20 amp fuse in the charging system.
