As I read all these reviews I realize that all the stories are the same. Including mine! We all got scammed! It makes me angry how they pretend to be a US company. I basically gave up on them and got PayPal involved which was a joke. They did not help whatsoever. This company knows how to work the system. Why do you think they send you your masks in parts? So they can claim they already sent them! File a claim with your credit card and/or bank. I did and I was reimbursed my money! As for the only mask I did receive (I was still waiting on 5 masks and a set of filters) I threw it in the trash. There's no way I would EVER use a chemical smelling cheap piece of crap!
