Product review (5 stars): Easy to install, good instructions, great modern look, vented outside pulls heat out of house very well.
Should have installed years ago.  Our gas oven vents heat into the room like a blast furnace.  Nice in the winter, but a nightmare in the summer.  Made AC work to much to cool downstairs.  Vented outside and running the fan on high moves the vast majority of vented heat out of the room to the outside preventing the kitchen from becoming uncomfortably warm in the summer.  Highly recommend this unit.
