I ordered a four mask pack with filters. Three of the four arrived and part of the filters. This was several months ago. I tried repeatedly to get the missing items. Inevitably, I received multiple automated emails stating my order was being processed. The few nonautomated responses I received promised the issue was being addressed. Needless to say, I never got satisfaction. I eventually requested my removal from their emails and promotional offers. I made this request multiple timeav request over a dozen times User's recommendation: Avoid this company and its inefficient ***.
