respironics dreamwear headgear with "arms"

Murray,
Probably too late now, but I previously posted a link to the Headgear with arms from Amazon on another thread with a cost of $17.00. It's helped me quite a bit in eliminating the slippage and is just as comfortable as the original. It seems to have done the same for other people, but I think it may depend on the curvature or lack there of on the back of your head. Also, the right size of the mask shell is important. Best of luck, and here's the link. I also started using tape and the result has been excellent, although nobody can top the results you're getting.

Thanks for the link. That is closer to what it is probably worth. Tried it for the first time last night and it was OK. I had an approximate 30-minute high leak period that I don't remember. I'll fine tune a bit.
