Let me start by saying this portable AC is a BEAST when it comes to cooling power. I tested it in my 650 sq ft apartment during a heatwave, and within 20 minutes, my living room went from sweltering to comfortably cool. The 14000 BTU rating isn't just marketing hype - this thing delivers.

The 3-in-1 functionality is where this unit really shines. I've used the cooling mode daily, the dehumidifier during rainy seasons (works great for my basement laundry area), and the fan mode when I just need air circulation. The remote control with backlight is super convenient for midnight temperature adjustments.

Now for the not-so-great parts: The drainage system is my biggest gripe. Like other reviewers mentioned, the drain port sits way too low. I had to prop my unit on a small platform to get proper drainage during humid days. Also, while it's quieter than window units, the 48dB rating is noticeable in a bedroom - I wouldn't call it whisper-quiet.

Installation was straightforward with the included window kit, though I wish the exhaust hose was more flexible. The auto-swing feature and wide airflow angle do an excellent job distributing cool air evenly across the room.

For the price, this portable AC offers impressive performance despite its minor flaws. Just be prepared to get creative with drainage solutions if you live in a humid climate!
