Fast and easy
The service, as usual, was excellent. I have purchased both KN95 sans valve and now those with a valve. Overall, the quality is equally good. However, several of my medical-field friends question the presence of the valve in terms of efficacy v the masks without valves. I will undoubtedly wear the masks without valves indoors and wear the ones with valves while walking or for any other outdoor situation.
Masks are comfortable to wear, reusable, and neat. Arrived quickly, and we are very satisfied
Came right on time, nice quality
Very comfortable and definitely easier to breathe in than regular KN95s.
