Review on TOSOT 10000 BTU Portable Air Conditioner with Remote Control, Built-in Dehumidifier, Cooling Fan for Rooms up to 400 sq.ft, Grey by Matt Kovacevic

But when I round up from 4.5, I settled on 5. The reason why it deserves a 5. Cools quickly and very efficiently, and the exhaust hose design leaves no room for hot air to escape Exhaust all the way through the hose window outlet. This was a big problem for my Whynter portable air conditioner due to its design. The reason I almost rated it a 4. It's the loudest compressor I've ever owned. I've had Danby, Frigidaire, Two Whynters and now this one. It took me a long time to get used to it at night. The first few nights it scared me so much that I had to use earplugs. Yes, after starting the compressor, the noise is not too loud. But it shakes the entire block when it turns on, and that can be an absolute deal breaker if you're a light sleeper. All in all a solid recommendation for an average room like mine.
