The air conditioners are very cheap. Mine was delivered quickly (straight from Poland). The operating instructions are imprecise as far as the installation is concerned. What a cheek in my eyes: To advertise with the 24 hour service phone. Of course, only a call center will answer (also on weekdays) that has no idea and says you will be called back the next day. Unfortunately, that doesn't happen (despite two attempts).
