all went well, it works great, a little noisy, however the room we have placed it is not needed to be silent!

I am using it, for the price it was a good buy!

I have a bedroom upstairs in a house with central air, and it always seems to be 7-10 degrees warmer than anywhere downstairs. This nearly perfect device does exactly as described. It helps suck more cool air up through the vent by using 2 small fans...
