I bought this style of AC because my cat has a suction cup window perch that I didn't wan't to move because he loves his bed.  When I saw this I thought it is a must!  No regrets.  It was easy to put into place and connect wirelessly to my Alexa.  It cools almost instantly and it is so quiet, sometimes I have to check to see if it is actually running (and it is).  Great find and a great buy!
