I can not give an accurate review on the cooling performance as we have not had any hot days until later this week. The remote control power button does not turn the unit on but it will turn it OFF! I have to contact Danby about the remote control. Install was OK but instructions could be more complete. Even though it is an inverter design and supposed to be quieter than other portable AC's it still makes a few noises when the compressor kicks in. I am not using it in my sleeping area so I will probably be OK with these sounds.
