Customer Review: LASKO 2138 8-Inch Dual Window Fan
AWESOME - how have i lived here all these years without this- Turns on when temp rises and the fans are independent - really nice and economical. The window it is in is IN the house, between 2 rooms. Put the Fan in the top of the window to help circulate air thru-out the house - works so well my utility bills are down by 10%!!
Customer Review: UNSAFE!!!!
This fan is extremely unsafe. I placed the fan in the window of my apartment only to be awoken by the smell of burning plastic. The right fan motor stopped working at some point in the night and became scorching hot. It was the second use of this fan after purchase. This fan is extremely UNSAFE!!!!

Customer Review: stop working after 1 month
the fan won't move just after 1 month use. I cannot find how to return this trash to the seller. It says the returnable date is over by Aug. 2. what the horrible situation....
Customer Review: I can blow harder!
Horrible fan, it is quiet because it doesn't move the air! I thought that is what a fan is supposed to do, move the cool night air into the house! This one, the air can be barely felt even on high, like I said I could blow harder. If you want to move air into a house do not get this fan. I got it because at the time of my purchase the reviews were good.
