I didn't want to chance my eyes over some Amazon or other non-certified safety glasses. I'm using this for my 45W Galvo CO2 laser and it's been working so far. The fit is perfect and even for my big head (think 4XL motorcycle helmet), it still fits. The wrap around coverage also does make me feel better. I do still stay away from the source by about 5-6 ft. Great price considering everything!
Great quality shield. Quick ship speed. Im happy to use this certified product over an a cheap amazon option. Works great with my prescription glasses.
Great product works fantastic!
