i have for over two years the lasko box fan that i use in bedroom and it works very well,but being an idiot when i came to amazon to order another one i was too lazy to look up my old order and ordered this one becuse "it looks the same".  its not.  the 3723 model from two years ago is fabulous.. really cools a mid size room.  this newer model you have to be within 2 feet to even feel any aire.  buy the 3723
