I have been using CPAP for 15 yrs, always had issues with mask, pulling to one side, jaw pain, and general dissatisfaction. Since switching to the wisp mask two years ago I get a much better rest, no jaw pain, and generally better overall comfort, or at least as much as you can have with trying to sleep, and use any kind of apparatus while sleeping. I use the style with silicone frame, and even find that the pressure imprint is less after a full nights sleep. I have to give this mask 5 stars.

I have 3 masks that I alternate depending on my mood. Wisp, Pilario Q, and AirFit. This one has the best seal, and slips the least. I highly recommend it. My son also uses it and prefers the Wisp over the Eson.

This is a terrible mask. It's loud, it leaks and worst of all it is poorly made. I have gone through four frames in the last year. Even though the company backed up it's product twice the frame still broke in under three months. Not worth it, looking into a new mask.
