1.5 years now with the same mask, thorough cleaning every day, the silicone hasn't worn out. The Velcro has worn out slightly but it was replaced with a button, very good fit on my face. I will probably get the same one again once it's out of stock

It does the job, it's very stable, as in not pliable or soft material which feels very firm on the face. It doesn't have a detachable tube from the mask which means you have to take the whole head gear off when having a panic attack, the good thing is, too stop any leaking, when tightening the mask, it doesnt leave too many marks of the face and not for long either.

I have bought this one twice and the F5 two more times. While for me it fits very well (the F5 not so much), it constantly breaks at the two upper hooks (the nose part) where they connect to the mask VERY easily and you end up stranded. Unfortunately, the company's head strap, both on the F5A and the other mask, the F5, is enough to drive you crazy. In just 4 or 5 months it becomes useless because the fabric that the 'velcro' grips on separates from the 'body'. (I will show a photo about this) I came to write this only because I am now looking for another mask and I don't want others to fall into the same trap as I did. P.S. As for the head strap, don't let any smart aleck jump in. I DON'T wash it so it doesn't get ruined. I wear a piece of sheet between the head strap and my head so it doesn't get sweaty from my head and get damaged. My own trick for over 10 years.

Mine has also broken at the point where the two plastic pieces join (where the headband attaches) on the mask, but I managed to glue them together in the end with epoxy; regular glue didn’t hold. The Velcro on the headband has also started not to stick, but they sell those cheaply from China.

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
