I appreciate how aesthetically attractive the Windmill is, and I can see a lot of thought went into making the installation process user-friendly. I also appreciate that the return was easy. But, a lot of people out there like me are experiencing the same issue where the temperature the AC puts out is 5-7 degrees higher than the setting. The fix support suggested didn't work (and the fix wasn't really clearly documented, which was frustrating). I am not sure the design choice to put the vents on the top make for the most efficient cooling, either. It seems you have some quality control issues at the moment, which I hope you work out.
