I had some issues with my previous Gold 5813 and I contacted customer service, they responded quickly, and responsibly took care of a solution. Sure enough, they did infact upgraded the housing of this lens and it's now much more rugged. I'm very happy with this lens and I even sold my Lincoln Viking 3350 to buy more of these because these are my absolute favorite now. The hand function for the grind mode is absolutely brilliant. Every feature of this lens makes my work easier and increases the quality of my work as a professional Journeyman Welder. I was blown away with Sofia who took care of my case and solved it promptly. Thank you so much. I'm officially a loyal customer. 10/10
