Sharper Image PORTAL Window Fan with Reversible Exhaust Mode

works fine - a little bulky and a little bit of an awkward fit into the window

This has been great. Works just like it should, and can either pull heat out of the room or blow cooler air in with a flip of a switch. Very happy with this purchase

Love this product very powerful and feels cool and love the reversible function and the foam included to fit into the window. Highly recommend!

Cooled the room quickly, as well as pulled hot air out as needed.

We love this fan. We have had many window fans and this one is much more attractive and higher quality. It works well and is very quiet.

So nice to have a small narrow fan in the window by my bed. Not too loud when on. Works great!

Great exchanger for small bedroom

My room is the perfect temperature

Waste of money! There is barely any circulation of air coming out of this fan. Sitting 5 feet away from it and I feel little air at all!

Low profile look but a powerful little machine! Love the versatility of this and it’s easy install into our windows
