The Vornado TRANSOM is easily the most powerful and elegant window fan I have ever had the honor of seeing or using; while being surprisingly quiet AND weather resistant!
As someone who sleeps hot at night, the strong, low height wind generated by the TRANSOM helps keep me nice and cool. Family and friends have also mentioned how much cooler my room feels now in comparison to the rest of the apartment while it is running. I absolutely LOVE it!
The unit is pleasantly lightweight despite its size, and installation required no effort once I figured out the correct orientation for the included foam blocks (the manual doesn't specify, so it took a little bit of trial and error). My only real complaints are that the unit lacks of any kind of built-in rear mesh or screen to keep mosquitoes and the occasional carpenter bee out (this is something I'd love to see added in future models or revisions along with an even more powerful speed setting), and that the touch (and even remote) controls can be a little unresponsive at times (I would've preferred physical buttons). The manual states to keep the window screen installed for that very reason but doing so is impossible on the apartment's thin to average size windows (as shown in photos).
Overall, I'd HIGHLY recommend this to anyone who wants a powerful window unit without the hassles of installing an air conditioner, or the noise of a box fan. I can't wait to see what future generations of the TRANSOM product line have in store if the first gen is THIS good!
