Great Product

I use these masks every day and appreciate the quality. Sometimes I'll use 2 or 3 masks per day depending on my activities. That the masks are made here in the United States is the reason I chose them to begin with. I appreciate that you ship the masks in boxes because the postal service keeps crushing the packages. The last box of masks that I received was crushed a it popped open, but the mask boxes were in tact.

Best masks on the market, and made in the USA

I bought these these masks for my firm - twice so far. They are very well-constructed, and fit snugly and comfortably, offering my staff superior protection. The price was reasonable (particularly in light of the quality), ordering was easy, and delivery was fast. I am also happy I was able to purchase this great product from an American manufacturer.

ONGO Returns Policy

Due to health and safety concerns, COVID-19 Antigen Self-Tests cannot be returned even if unopened and no refunds will be issued. Accordingly, all sales of COVID-19 tests are final.

PLEASE NOTE EXPIRATION DATES BEFORE PURCHASING. Currently, the test expires on the last date of the month printed on your box (i.e. January 2022 means January 31, 2022). However, with medical products under EUA, such as On/Go, the FDA, after close studies, grants rolling expiration extensions. We expect the expiration date to be extended before the end of January and another expiration extension again early in spring. We will continue to closely update our website when the expiration date gets extended.

DemeTECH reserves the right to remedy customer issues and concerns on a case by case basis based on the facts and circumstances of each customer.
