Honeywell MN12CES (3.5kW)

It is easy to install and efficient on reducing the heat in the bedroom, only down side is the noise from the cooling but was sort of expected from this kind of machine. The menu indicate you should consistently check if the water level in the machine is overflow but it never happen to me even I used it at least two nights a week for the last summer.

the cooling performance is quick.
the portable unit look very minimalist yet modern, installation pretty easy but the air con hose not long enough because they only give you 1 meter.
the unit are bit loud if you put it in the bedroom, but if you able to sleep with people talking around you that means this machine noice not gonna effect you.

I was reluctant to buy a portable air-con after reading all the negative product reviews for all brands. Got a good price for this one, was assured it would cool one room (and one room only) and they were right. So far so good, it is great and has got me through this hot summer. Yes its noisy as it cuts in and out but you get used to the background noise. I like the look of it too. Can't move it up the stairs as its a bit heavy (tempted to get another for the bedroom) but so much easier and cheaper than getting a fixed air con in the wall.
