I bought and I'm happy. Nice workmanship. The possibility of grinding - the knob next to it, not in the mask as some models have.
After a few hours it lies well on your head, at first everything is a little stiff but it's a moment. Setting and mounting the mask is also cool, it does not fall off the head. Maybe Chinese but looks really nice. It's great fun to do this. I welded for 1.5 hours with breaks, my eyes didn't burn or hurt. The only thing that I think is very weak is LED backlight. Don't count on it

It's just weak that it pisses you off. Generally I am an amateur of welding but I am happy.
Well, take into account the 3-year warranty, i.e. if it breaks down after 1 year, you will probably get money because this type of mask will not be available for sale
