This mask leaks too much, i don't understand how this happens, the f10 model operates without leaks at pressure 16 but the last model f20 makes leaks from 13-14 pressure. Maybe the mask size is not correst. Grigor, Pazardjik

wonderful full face mask, would recommend!

Thanks for the quick delivery, keep going guys your service is really impressive, James, Oklahoma city

very good mask and service, quiet mask, comfortable, it makes some marks on the face but not always, i am very happy with it, WAI, HONG KONG

the seal not perfect. i have leaks at night almost at every night when i sleep. but good with no noise.
