I'd give zero stars if possible Charged me $73 for 10 masks which are now offered at $30. Took months to deliver. The masks are not usable. KN95 masks with an exhalation valve. You can exhale but you cannot inhale. They don't have a customer service email address. Emails to them bounced back. The email address that PayPal has, they never answer. They lied about being an American company. On the website it still says that they are based in Temple, FL. They are not. If you're unhappy with your purchase, you have to return to China to get your money back. That will cost more than the items you received.
