Review on 🔲 LINCOLN ELECTRIC KP3775 1 Auto Darkening Variable Helmet by Matthew Aiono

I've had four different 2x4 Self Dimming (SDL) lenses and this is definitely the best. This is Lincoln's first SDL. I bought Amazon guarantee offers. It's quite expensive and seems like good insurance as the other four lenses only lasted about a year before starting to fail. I've only used it for TIG welding so far and it works great with filter on speed and on (no flash) and dimming. I charged it for about an hour in sunny AZ and it was ready to go. Be sure to use clear lenses inside and out.
