Bests & Worsts Reviews from Amazon

So I don't write reviews but I believe for this kind of product it's a little scary because about 50% of KN masks are not protecting the consumer because of either bad stitching or they are not using the proper materials. For the amount of money we are wasting we need real reviews with proper feedback. Ttimes like these it's hard to let a dollar go to waste.Okay, so I just received mines and immediately went and did the water test. For those that don't know, you want to do a water test to make sure droplets aren't going in nor are they coming out. So what you do is put water inside the mask and hang it by the ear handle things and keep it there for a while. If you see water coming out even a drop then that represents a leakage and it's no good. So far I'm about 10 minutes in and I see no leakage. If I see any I will update this review.This review is for the Black KN 95 mask 20Pcs
