HIGHLY DON'T RECOMMEND! !
I work on a large construction site, I took a mask in appearance and reviews. I worked in it for three months, I decided to test it and leave a review.
ABOUT THE MAIN - the light filter sometimes turns off by itself, the blackout is partial in the center, the eyes get very tired and hurt. Offhand it works like a mosquito for 1500r only with bells and whistles. Wasted money.
