I bought 7 protection masks against the coronavirus, I had problems with one of them that arrived defective, the metal part that is squeezed in the nose was broken, since August 4 I have not yet received the refund for the return, they do not even answer to emails. In addition, the mask will be good as they say but to be a product with these characteristics I must say that the metal part has already broken in 3 of the 7 masks, in addition to the one I returned, which seems unheard of given the characteristics of the product that also It is certified by various scientists. I am honestly very unhappy.
