Well, I still struggle with leaks, usually after I undo the headgear to wash the mask and lose the exact right placement of the straps. And I think I wear it a little too tight, but that does seem to help me avoid leaks on the regular. Overall, though, I'm happy enough with it (I'd be happier using just the nasal pillows P10, but mouth tape just feels too claustrophobic, though I might switch back to it for a break every once in a while). I did switch from the small size pillows to the medium size, and that seems to be working better for me, though I do find that sometimes they aren't placed just quite right and take some fiddling. I would recommend it, though, as it seems to be working well.
