Query: A huge mistake

I have recently bought two of these masks, one for me and the second for my wife. The main problem we have with them are the thick straps that cut through the ears. The mask is also so thick that it makes you so hot during the night, and you have no choice but to take it off. I will try to refund them and find something else here from Amazon.
