Starting out as a new CPAP user, I like this mask because there is no guessing as to what size you are. In your original order for the mask, you get all 3 size cushions. You pick which one fits you the best and then you know what to order next time. I also like this mask because it fits under the chin, most mask aren't like that. It helps keep your mouth closed, while you are sleeping. GREAT feature.

Love this mask, only one I can wear. Perhaps the people with leaking trouble might just loosen them a bit. My Dr. told me with the full-face a little leaking is OK, and I am at a very high pressure. Unlike my husband, who has a nasal mask that is not suppose to leak :o) Just a thought. I've been lucky enough to try the ultra-comfort gel kind and I cannot use it at all ~ weird, different strokes I guess. Anyhow, worn mine for over a year, last one a bit longer than that!

The silicone seal is very fragile and easily broken. Mine broke completely into within the first month of use. The break occurred at the top of the silicone seal where the mask contacts the top of the nose.

I received the c-pap machine years ago from the V.A. They send me masks every six months, that vary in types. By accident, surfing the internet, C-Pap Supply showed up. The mask, I was using, would rise up to the point the bottom would be at my bottom lip. I talked to a Rep, she suggested the under the chin mask. Two months now and the problem was eliminated. Great mask! Great company. Thank you, C-Pap Supply.

I have been using the same mask with the original cushion for over 6 years now. I have never been happier. All of the fit and leakage problems disappeared when I tossed the manufacturers head gear 5 years ago and made my own out of 2-sided velcro tape. The fit is now perfect with no leakage. And I toss around in my sleep! But the upper strap support on the mask finally broke. I fixed it with crazy glue but I'm taking no chances. I'm replacing the mask today. After 6 years of use, abuse, and travel. It's due. Want the cushion to last? Clean it with plain warm water. Only use a very mild soap about once a week.

Finally a mask that fits under the chin and no guessing game with the cushion size. You get a small, medium & large Cushion.

Excelent mask. I have tried different mask but the fisher is the best fit for me. I dont have to over tighten it for a seal as a matter of fact I have noticed that if I over tighten any of the mask they will leak. This one is comfy and with the slider strap stays in place when I roll around.

I'm on my 2nd mask, it is weak where the top head band support joins the mask and it breaks easily. I repaired it with wire and epoxy and continue to use it. I had a seal break but that was after months of use. Overall I like the mask as it seals well.

The mask seems to work well for me. No seal problems yet.I am on my second though, but not because of problems. The first one simply was worn out after 9 months use. krw INDIANA

The mask is weak and easily broken where the top head gear support attaches to the mask. I've had two break at this location. Otherwise, I like the mask.

I have been using this mask for almost 2 years and it is very bad about leaking. If I tighten it then it digs into my face. If I move my mouth it leaks. I need a higher air volumn but this masks cannot hold up to it. Looking for a change.

So far I've tried every full face mask and they all leak. I am still tryihg the Fisher & Paykel HC321. I suppose I'll have to give up trying to use a pap machine as bad as I have sleep apnea. Sham I can't get a custom made one. I am a mouth breather of course. Oh, I'm using a Respironics REMstar PRO2 C-Flex. I've tried a bi-pap, c-pap and now a C-Flex. Still cannot get any sleep. Might could if I had a mask that didn't leak. I have tightened it so tight it was painful to keep it from leaking and because of pain I couldn't sleep.

Best mask ever. I've used so many and my search is over. I love this one. I can sleep on any side and 0 problem even on my belly. Adjust it ones and that's it.

I have been using this mask for quite sometime now. At least once a year I have to replace the 'whole' mask because the non-breathing valve comes loose and causes a bad leak. I've tried to glue it, but to no avail, still leaks. My insurance covers the cost, but it is expensive. Can I not just get the part needed, the non-rebreathing valve? Also I have a problem with severe indentation marks on my neck and cheek area from the tight fit, embarrassing.

I've been using this style of full face mask for the last 6 years. Have had about four masks (same style) mostly because as they age out different parts break or the mask comes apart at different locations. Notwithstanding that, I find the mask very comfortable once I get the head gear "tuned" to my head. I sleep on my side on a regular pillow and very rarely get leaks. I recommend this mask every chance I get. My wife recently was diagnosed with OSA and was issued a Res Med mask by her medical equipment provider and has had problems with its fit. Can't wait to convert to this one. Great product.

I have a small face and head.I mouth breath as well as move around at night.I have tried other masks but this works perfectly.The true test was when i got to put my machine away for 2 years but then had to use it again and the mask still worked perfectly without even needing adjustment to headgear.

Not real happy about this mask. Seems to be loose, when you tighten it, it digs into your face. On a positive note, it is one of the only masks, that go under your chin. Take the good, with the bad. Try it for yourself.

Stop using Bi-PAP years ago due to nasal masks...air came out of open mouth not into lungs. Now Have FULL FACE MASK... I give it 4 stars due to fact that the bridge of my nose is VERY wide and cushion fits as according to design of the solid plastic that holds it. It could be a bit wider to stop "pinching" bridge of nose for me. But I sure do APPRECIATE it hugging my chin and stopping the air coming out of my "open mouth" while I sleep. Seal is great...I am happy to have the use of my Auto Bi-PAP again.
