Reliable air conditioner that keeps our living room nice and cool even though that part of the house is under the sun nearly the entire day.  It is relatively easy to install, however, it doesn't take into account different window types or sizes.  I had to buy longer screws to fasten the A/C frame to the interior sill, and longer bolts used as supports for the outside sill.  Other than that it works great.  Really happy with my purchase.
