I bought this for a welding class thinking I need something economical, nothing major at the moment but am amazed at its quality. It has a spacious window, the instructions are easy to set up, and it's easy to maintain. Fellow students have more expensive face shields, but this one really competes with theirs. You might want to buy branded batteries, mine run out quickly, but that's a small price to pay. Love how easy it is, my teacher encourages us to set up our shields.
