Window type aircon (1.5HP) for 15sqm room

Hello, looking for any recommendations/user reviews among this list of air conditioners. Currently the room would not be able to accommodate a split type due to water drainage piping and mounting issues so i'm stuck with the window type one.

may naka gamit na ba sa inyo nitong mga aircon na ito? kamusta ang after-sales/ performance? planning to use the aircon approx. 9hours a day @ 24C temp

PANASONIC CW-U1221VPH

any help/insights would be appreciated :)
