Unfortunately, I did not read any reviews. It appears transparent in the photos. It is not! You cannot use it to do any work, so I don't understand why it was made! The plastic is dull and scratched because it touches without protection in the packaging. I bought it for more protection in classes, over a surgical mask, but it doesn't work at all. The frame is good... but the visor in front is terrible. It is not suitable for the reason I bought it, but I won't send it back because it is not cost-effective with the shipping.

Zero, as a nurse I bought ten for myself and my colleagues but they do not live up to what they claimed, visibility is blurry, I had a comparison measure from other masks I use, and one of the boxes they sent was missing.....with the same amount of money my colleagues bought better ones, and the shipping cost was 7 euros.
