I've had one since April. I'm not a professional, just your average backyard welder. It was the first welder I bought, but I have used a few others in the past. It's been great so far and has helped me complete some projects and repairs. One of the features that sold me was that it easily converts from 110 to 220V. Figured it would be nice to have the option to use 110v if I needed to take it out of my garage and where a 220v receptacle was not available. It also wasn't priced much more than a 180 range unit. (at the time Miller was also offering a rebate of about $150). I would definitely recommend it!
