Good product for a good price.
I bought this to heat and cool a 400 sq. ft. addition in our house. I had looked at several options, and a ductless mini split system seamed to do the most for the least amount of money.
I got two quotes from heating and air companies in our area that ranged from $3,700 to $5,200 for the unit and installation. I thought those prices were ridiculous, so I did a little research and found this unit. Because I was able to buy it myself, I did a lot of the install myself and save A LOT of money. I

poured a concrete pad for the condenser to sit on outside, installed the mounting plate, drilled the hole for the lines, and ran a new 230V line with conduit to the unit. I made some calls and was able to find a professional that was willing to come in and just set the lines and finish the install. So the total install price was under $300, plus about another $100 for electrical supplies.
We have had the unit installed for about a month, so I can't report on the electrical bill just yet. I will say that it is almost silent, it's tiny and almost un-noticeable on the wall, and for the most part does a great job heating our space. The only problems we've run into is that the temperature outside has been in the single digits at night and low 20s in the day and it has a hard time keeping up at those temperatures. I read this in the owners manual (which you can download right here) before I bought it, so it wasn't a surprise. This is abnormally cold for where we live, so I expect it to function just fine once the temperatures come back up a little. I should also mention that our addition is un-insulated CMU construction with an un-insulated tar and gravel roof, so it is a really hard space to keep heated. Even at these cold temperatures it is still able to keep the temperature in the room around 64-66 degrees.
We have not yet used the cooling function, so I cannot review that, but from what I've heard and researched, I expect it to work well.
This unit has a SEER 20 rating which is awesome. Based on our local price of 8.8 cents per kwh, I've calculated that this unit should only cost $130 per year to run. I will have a better idea after this winter and summer if that is correct.
Two small complaints: I wish it came with some sort of protective sleeve for the lines that run through the wall. I had to jimmy a sleeve and I'm not super stoked about it. Also, the electrical line doesn't come with water proof connections for the condenser. I had to go and buy those separately, but it seems like those should be included.
That's all I got, hope that helped.
