Someone just came into my shop asking for one of these. Never heard of them. Anyone have any experience or insight with these?

and do they work?
This doesn't simulate being at elevation, it just simulates breathing through a straw while looking like Bain. It would be pretty awesome though if someone could shrink an altitude tent down to the size of mask.
weekday about something that would only cover your nose and mouth that would simulate altitude? I'm sure it's possible, and much more cost efficient!
