This is a fantastic unit for a small bedroom/study. I got them for my children’s bedrooms that were utterly stifling in the summer heat. The window kit isn’t the best and we ended up fashioning a more sturdy model out of timber, however the unit itself works very well, has a quiet feature and cools the room very quickly.
It’s not quiet by any stretch, however my kids are used to white noise type sounds and are able to sleep soundly with it on. The unit will cut out automatically once the set temperature is reached and the start up again if the room heats up, which is a great feature, although the sound of it starting up again has woken one of my children up. For a portable unit I did expect it to be louder and perhaps not as efficient as it is, but I’m so far pleasantly surprised. We will see what the electricity bill brings, but for the comfort it brings my kids during the Australian summer, it’s worth it.
