I bought this for my daughter's college apartment.  Set up was very easy.  I had to trim one of the panels.  I was able to trim it easily using tin snips.  The only problem I encountered was that the exhaust tube is not long enough.  My daughter's apartment is partially below ground so the windows are high up.  I had to elevate the unit using 2 milk crates.  There should be an option for a longer hose or a hose extender.
