Received mine today! What a great company and masks are fantastic. The quality looks very high-end exactly how I was wishing it to be! Customer service is so important to me and the Sterviral team rocked it! Before placing the order I had some concerns about the heating in the mask so I checked with them and they explained to me in detail how the mask works.. I would definitely recommend this to a lot of people as it is a one-time investment and a better and safer option
