"A pricey bit of kit for what it does only relatively well. I held off purchasing it for a while but decided it was worth a shot as I've had several ceilings to take down as well as removing old plaster off the several large walls. Couldn't say it performed badly, just that It wasn't nearly as effective as I'd hoped considering the cost. I reckon a normal fan would do just as well for much less! The ducting was more trouble than it was worth and also a nightmare to clean up! It has a powerful motor that feels robust but doesn't create as much suction and flow as I'd hoped. My overall advice, my a cheap desk fan and save some pennies!"
