Mask smells very unpleasant plasticky ....

As such, the device is just fine, both the performance and the price. The big disadvantage of why I will return the unit also is the more than stinking uncomfortable mask. Both the adults and the children's. Both masks smell so rough that a (in this case me) prepares Inhalation headache after plastic.

The smell also went after several clean, disinfect and ventilate not gone. The mask is flexible and adapts to the face or mouth area. Presumably it is the plasticizer of stinks so bad. For me, an absolute knockout criterion. One thinks one effect after inhalation what healthy and feels like it as if you sat over burning tires.

The volume is too high for such a small device.
