much better than the one that ties at the forehead....as well as the nasal one which, when the mouth opens during sleep, creates a strange sensation because air passes with pressure from the nose to the mouth....

Very good for its price, I have tried masks that are at least three times the price of this one and I didn't see a difference in use, the big difference is in the quality of the headband (it frays and comes apart in 6 months at most) it would be good if there was a replacement available.. But compared to an expensive headband from a brand that costs 35 euros and still breaks down at some point (within a year, maybe a bit more..) the mask is a good choice as a purchase.

It is clearly better than the other one that sticks to the forehead. My husband used to wake up often with marks that were still visible until noon. It doesn't seem very sturdy. It will probably break in two years like the previous one.

It really worth the money and it works very well. Consider how a mediocre mask of this type starts from 70 €. I highly recommend it without hesitation

From the beginning, you feel discomfort in the back of the head and on the sides.
You have to tighten the retention straps quite a bit to make good and proper contact, but this brings discomfort after several hours of use.
After a short period of use, the straps start to lose elasticity and become unlocked enough that you have to try to tighten the scratches as much as possible until they completely wear out
