“CPAP masks are WAY over priced so that is the only reason for three stars. They all get three stars. However to the mask: The F20 is the best mask on the market as it will fit every single face and head shape. Some people like me who are lacking the backward sloping neanderthal head shape cannot wear masks that brace of the forehead. Besides.. these things are claustrophobic. The F20 silicone fits beautifully.. no leak even at very high pressure and the new diffuser valves on them are dead silent. So if you say.. have a Fisher and Paykel Sleepstyle machine with one of these masks.. a person could sleep beside you and be oblivious to the fact you are using CPAP at all. They are also very comfortable. The only advice I would give is to size SMALLER than what you need. I use a medium FOR HER as the head straps are always too big otherwise. Medium is a great size and I am not a small man standing at over 6 foot tall, and weighing 140kg. I have not tried this with a beard but I do intend to grow one in the next few weeks. The neck strap.. however.. and this is common to all mask straps (head gear) digs into the base of the neck. 4 strips of craft foam, cut to 3c x 10cm, layered on top of each other and wrapped in clear wrap, is ideal to insert between the strap and the base of the neck. NEVER over tighten your mask. Pull it off your face for a moment to allow the cushion to expand esp over the nose. Then... get a good night sleep. As for lasting.. I get 6 months out of the head gear and about 18 - 24 months out of the cushions. I currently have three as I do buy a new mask every 10 months or so as they do lose their stiffness over time.”
