I ordered this over the winter and just set it up yesterday, so I couldn’t give a complete review until now ... this unit arrived packaged very well and was in perfect condition.  With a different unit that I have, the hose “snaps” into place at both ends (the back of the a/c and the window panel), this exhaust hose screws into place.  Not a big deal, but a little awkward. Other than that, which I’ll admit is minor, this a/c works perfectly, is attractive, easy to use and most importantly works great!
