Leak Rate Question (OSCAR)

[Canuck 2]

P10 is a excellent mask and have used it for last 5 years and it does leak but not really that much during my sleep. Head gear is only good for 2-3 months and has to be heated with hot water and cooled quickly to regain its original length in a coffee  size mug. Also you can use the n30 head gear band(adjustable) on the P10 mask that I recently found out(part# 64216).

I use this hose trolley system for many years and it works OK and it is above my head that I prefer.
