“The weight of the air vent in this product is too heavy, and pulls the mask away from my face, breaking the seal. That in turn affects my results. The N30 cushion itself is one of the least intrusive, so it’s a pity the mask connector is not up to scratch. The N30 mask connector for machines other than the AirMini is much better designed but doesn’t fit the AirMini (except with a DIY hack. ) I guess I’ve paid a lot of money to find this out.”
