Great value, works great!
I installed this unit into a sun-room that is still under construction, so it allowed me to install this over a few days versus all at once and to build everything to suit my needs for this unit.
Electrical: I installed a 20 amp breaker at the breaker box and ran a dedicated 12 gauge line to the unit. Instead of using an outside A/C breaker (which is slightly confusing), I installed a 20 amp double pole light switch for the cut off. The double pole is a true cut-off because it kills both the

positive and neutral supplies. The unit itself rates between 15 - 20 amps, therefore I opted to be safe and just go with the 20 amps.
As vaguely explained on the electrical panel cover, brown is black (hot or positive) and blue is neutral (white), and yellow/green is the ground on the provided cabling. You'll notice the empty slots on the right side of the compressor unit, though based on the diagram in instructions, it seems backwards. Pay attention to the letters on the diagram and the compressor unit, which should help you locate the correct terminals to screw the connectors into.
Piping: I had to have the pipe cut and flared to the correct length for my installation by a neighbor who works with copper. After vacuuming out the line (the fitting on the bigger return pipe is of a different size than a normal A/C unit, it's a 5/16" flared fitting), I opened the valves on the compressor and I energized the unit... quickly discovering the pipes were leaking. I shut it off and tightened, but still had leaks. I did not want to over-tighten the fittings as recommended. So I called an A/C guy out and he tightened the fittings more, added some of the lost coolant back and kicked on the unit. Cost me less than $200 bucks. It was worth a shot trying to do it myself though and it didn't kill anything. Better than paying $1000 - $1500 to have someone else completely install it.
The unit blows very cold air and enough to cool my sun-room. The remote is basic but takes a little getting used to because the buttons and symbols are vague. Aside from the hiccup pressurizing the lines I did everything myself and I would do it again.
The only con is the instructions, which cover numerous models.
