By cons noise level is really very very noisy, the indoor unit even "slow" mode lets a noise impressive wind tunnel that will you speak up or increase the volume of the TV (it is not even hear the compressor so the blower is powerful, indeed the 3 different levels do not have much margin for me it would be "strong", "ultra high", "supersonic")
As for the outdoor unit, blower and especially the sound of "sizzle" will cause your neighbors to close their window, however, the compressor being internally, the air conditioning is totally allowed. So personally I use it if it is over 27 ° inside, and at night I prefer opening window if possible, after if it bothers someone, you'll still legally!
Minor complaint on the remote control unnecessary personally because it only works "high", not on the sides or bottom, even to 2cm of the device, I said that I put new batteries ^^
For the drainage of condensate, indeed, after 1 hour of use, it is full, however, as indicated in the instructions, the system uses the water in cooling mode to better cool, I empty So never, the unit starts also never in "bin full security" as some, there is only a little water comes out of the outdoor unit (through a small hole, again as shown in the instructions). The hole of the internal tray is used for water drainage when using the air conditioner for several more months, again as shown in the instructions ^^)
So I suggest for performance and yet, if you have a well-insulated house, the cold will stay several hours at home even after the air conditioning off (22 ° to 24 ° 3-4 hours after stopping the air conditioning, return to 28 ° after 5 am)
