A while ago I actually bought (gulp!) some mask liners, but find them **way** too much hassle to use.
I am now trialling one or two Hybrid masks for a while and want to revisit mask liners or just the idea of them.
So....
Does anyone have data on what the Mask Liners actually do?
Do they actually Eliminate Leaks? (Oscar Leak Rate data would be nice, pretty please...?)
Do they effectively Reduce Leaks (data would be nice!)
Or do they only make it Feel Like there are less leaks, sorta acting like a muffler?
Does anyone feel they make the Leaks Worse?
Be interested in your experience, feel free to share.
Chris.
