I had been searching for a good hi-tech face mask and found this online!!!! The Ithas is an amazing facemask. Especially the fact that I can adjust the temperature in it and the USB control cable is detachable. There is a magnet in the mask that helps me securely fold it and not leave it open when I am not using it. The black pouch fits in the mask, battery, and cable very easily and is also a great option while in this damn pandemic!!!! All the features I get are totally worth the money!!! MUST TRY!!!!
