One box, one opening, quicker and cheaper to fit, and you can take it with you. What's worth paying for here is the build: 100% copper on all three parts of the circuit, not just the condenser, plus Blue Fin coating — that's what survives Delhi air. Auto restart with memory means no hunting for the remote after a power cut. Two honest notes: the compressor sits in the room, so 56 dB is audible, and you must check your opening size before ordering.
