These are really nice helmets for the money. And everything about them is shockingly good value. However, I only used my helmet once before asking for a return and refund. The helmet worked great when I fired up my Miller mig. Absolutely excited about it after using it the first time. My previous helmet was a yes welder brand as well which ran perfectly for years until part of the screen stopped darkening. But this one, for whatever reason, no matter how much I played with sensitivity and settings, it seemed to struggle TIG welding and often would undim while I was still in the arc flashing me. The only way to alleviate this was to turn the sensitivity all the way up which totally negated having an auto darkening helmet because it would just be dark due to the shop lighting..
Surprised on the quality of how you see your welds
