Bests & Worsts Reviews from Amazon

First thoughts was impressive, looks well build and easy to mount. I made a frame to mount it to that I can place in the windoframe without damaging the window casing. I brought it inside and turned it on. Low was great, quiet and move some air. I decided to crank it to max and that's where my disappointment started. This thing shook the window so much it could be felt dow stairs. I will call lasko (the company listed on the motor) and see what they can do. I would rather not have to send it out because of the size of the box but if they do something worthwhile I will update the stars. What a pain to try and balance the blade, got close but for the price of this. STAY AWAY, not worth the hassle and frustration when you want to use it as designed. I'm looking for an external supplier to buy a new balanced blade from but with a 10mm shaft, it's hard to find one for a 20 inch fan
