Coolblus Portable Air Conditioner (Open Box)

Ineffective: I got the 10,000 BTU unit which claims to be able to cool up to 450 sq ft. This thing is unable to cool my 144 sq ft bedroom. I had it on max cooling settings (61F + Hi-fan) for 4 hours straight and my room is still above 85 degrees. I am still sweating from how hot my room is. I have to stand directly in front of the fan in order to feel any cooling. Inefficient: Massive amounts of heat leak out of the heat pipe. I was wondering why I kept feeling waves of hot air when I moved around the room. It's because of the radiating heat from the pipe. I tried covering the pipe with aluminum foil which helped a bit. But come on, this amount of heat leakage is insane. You're essentially heating and cooling at the same time. Noisy: The product listing description is blatantly lying about 52db. Imagine the booming hum of those old refrigerators. It's that for almost every setting. It's either loud or very loud. Deserves at least 1-star for its decently easy setup and working remote. I have no idea how this product is getting 5-star reviews. It is failing to do exactly its purpose. Please review this product honestly and critically so it helps other shoppers.
