I had to give a 1 Star because ZERO stars was not possible. This $30.00 piece of junk arrived broken. Very poor workmanship. A $3.00 Walmart mask is BETTER than this pathetic mask. I waited for a week and was impressed enough to spend $30.00 on a MASK. There was clearly NO quality contro, l used at all since the mask strap was broken right out of the bag. I never even got to wear it. Germless? More Like WORTHLESS!
