I think you get what you pay for. I had a lot of trouble maintaining the mask between jobs, the mask has good fitting points but it could have been made from a better material. No complaints about the dimming function, I was very happy with it.β¦ I'll probably leave it to someone to look at, but I need something of a higher quality, it was easier for me to remove it between welds, which was a real hassle. Our instructions are also very incomprehensible, if I had to do it again I would not buy this product.
