the coat of the copper tubes they give is so shit
just by looking at it disintigrates to dust and I did not even put it in the wall
also the end bit thing you twist to connect the tubes are like 1 milimeter smaller in diameter so I cannot use regular tubes with proper coat
and they use too much tape everywhere in the packaging
it is anoying to remove it
if you really want gree then just buy nord
same shit but easier to install less pain
hayer is nice to install too, it does not needs full disassembly of the indoor unit to connect the tubes easily and connecting the cables
