| That's exactly what I thought when I saw it. Why scrimp? As show above, an actual O2 kit isn't that much more expensive and oh so much more benifitial. When I first read it I thought they were instructors that had recognised a need.
Don't get me wrong, it's a good idea, but they really should have done a bit more research so the unit was O2 clean in the first place, and that's going to put the cost up. |
