I would imagine it's easier to reverse the direction of the airflow than a recoil sucker.

Ok now i'm confused. Isnt a recoil sucker like a pen, Press the plunger down and then hit the release button to suck?

They look very different, the sucker has a trigger to turn on the pump, the blower is permanently on so you can set the flow and temp.

I got mine cheap on flea-bay :beer:

I'd better start looking then. Any makes to look for or avoid?
