Has anyone using the hybrid from last year and then got a newer one??
did you notice the holes on the exhalation are smaller and the flow chart included has less flow out of the exhalation
I wonder if the older ones leaked too much causing a drop in pressure.
any thought much appreciated.
Hybrid early models 06 vs newer models 07
