Review on CANAWELD Darkening Optical Welding Infinite by Scott Rao

So I wanted a nicer welding helmet. As I use a canaweld TIG welder I decided to upgrade my cheaper YES WELDER helmet to this one. Well the first one I bought kept dimming on and off! Causes flashes and flickers on the screen. After browsing the forums and doing some research, I doubted this and replaced the batteries with new ones. Still shit. Then I tried charging it under the sun... no better. So I returned it and wanted a replacement because I think they have good stuff and it was just a bad helmet. So today I got a replacement as I thought everything should be fixed. In short, SOS happened! I've never had so much trouble adjusting the helmet's parameters. Same $#i7! My eyes hurt just from using it. Don't buy it.
