Im sure my office manager uses it, I have never personally used it, but we built the new building and with new buildings {especially metal covered block} you get a lot of dust for some reason, and my comp system hates dust, actually had to add a/c to that room because it gets like 20 degrees warmer in there compared to anywhere else in the building for some reason, and then the repair guy comes and thinks nothing of charging $3000 for some stupid black box that no one can engineer to not run at 3 degrees under the temperature of the sun, and I could probably do everything that room of boxes, wires, and fans do with a pair of iphones...
But anyway rant over, sorry.. Back to the blower, be careful not to get it stuck, that would be an embarrassing Emergency Room visit...
Im still waiting for the thermostat review...
