The unit cools well, but the fan motor or fan motor power management is louder than the compressor! The distinctly audible motor hum makes the lowest F1 fan setting too loud for sleeping. The hum diminishes slightly on F2 and F3. Also. I had to use some of the translucent blue packing tape on the ends of the air filter handle to stop it from buzzing. I don't use the WiFi. Disappointed overall. My nearly 10-year old LG LW1011ER blows ice cold and quiet. This new unit cools well but the motor hum and handle buzz ruin the LG experience.
