Quattrof fx mask (verified owner) –
I am using Quattro FX for more than a year and it works very well for me.
It fits well and most of all does not leave red marks on my forehead. This mask helps me to sleep better.

Fits for a little time! (verified owner) –
Fits well with no leaks for a short period of time, and then starts leaking again. This product is good, but for a short period of time! NIKOLAJS from Tallinn-LATVIA.

Replacing my silicone for Quattro FX (verified owner) –
I am using the Quattro FX for a couple of years and couldn’t realize how much difference it makes to use a new silicone replacement part, it fits so easier on my face and I have no leaks at all. The headgear remains longer, I have 2 additional headgears in stock and don’t need a third yet. Phillipe, Touraine-France.
