Have had mine for over 3 years now and works like a charm. Has a little trouble switching in tight real low amp tig situations where you don't have a direct line of sight of your weld.
ProsAutomatically switches, has weld, torch, and grind modes. All digital display
ConsBracket that holds it in place is cheap plastic and breaks easily in cold weather, has trouble switching in low amp tig situations ( less than 30 amps )
