Be aware!  Mask does not allow for a good seal
As an EMT, and as someone who has tried to use two of these in the field, I can tell you that it is EXTREMELY difficult to acheive the required good seal between this mask component and the patient's face.  If you insist on risking not being able to effectively bag a patient by carrying this device, at least buy an extra high quality mask to carry with it.
