I've been using this mask for a week after Phillips Resperonics discontinued the only mask that really worked for me after trying about 5! I'm a flip flopper and it's hard for me to find any that really hold a seal over time. So far, this one has worked pretty well. I don't really like the fit as well as my old Phillips mask that had the double silicone seal...this is a single. But it is at least a somewhat suitable substitute. Although they don't recommend tightening the head strap as tight as I have too to maintain a good seal throughout the night. I refuse to go with another Phillips brand after they DC'd my other model, (which I had spare seals for, but can't acquire new headgear now) no doubt, in order to profit from a completely new product. This one is worth a try.
