Got this helmet when I started taking welding classes, took a combined 6 months of stick, MIG and TIG, got a job after I got done with classes, have been there 3 months. Simple, passive hood. Replacement Filter and cover plates are easy to find, and inexpensive. Some melting of plastic has occurred from coming in contact with fresh welds, but nothing serious. Headgear is very comfortable, easy to use and after almost a year of use, it still locks up, out of the way, and headband still locks tight to my head. Great value if you're not willing to shell out for an autoshade helmet.
