Does the job - noise level is acceptable. Annoying use of white LEDs.

The device does what it is designed to. It's not silent, though within the level of noise I was expected. It's white noise so personally I can sleep through it. With the recent heatwave of 36*C night the room of 30m2 was cooled within 30 mins to a normal 21*C... I slowed the process by standing over the Unit and having the air blow over me! The picture of course does not show the MANDATORY pipe that is needed to send the hot air out of the window (the photo wouldn't look as good). This pipe is the same as the back of the old-style tumble dryers. The pipe increases space usage, though not by much. For typical Swiss side opening windows you will need to buy an additional nylon fabric window seal with zipper. The material fits around the window, the pipe fits through the zipper and this prevents hot air from re-entering the room. The LEDs on the unit are bright white, though dim slightly when in night/sleep mode. Which idiot thought white, or blue LEDs on any electrical device that may be used at night is a good idea?! This illuminates the room at night. I solved this with my usual solution of covering the LEDs with a strip of clear red plastic.

+ Does the job, cools the room in a good time.

+ Wheels mean it can be pushed to new location easily

- White LEDs are really annoying...

- As expected: very heavy.
