I looked for months for an air curtain that wasn't "INDUSTRIAL", I wanted one for my residence, over the garage door, so in the summer I could leave the door to the house open and keep the skeeters out, but without it blowing your head off as you passed through the wind current.  This has two settings and the lower one is almost perfect, still a bit strong for the girls with their hair all purtied up, but there are going to be no skeeters in my house.  I did not use the door switch, as I only want this on when it's time for bugs.  The mount is very functional and very easy to install.  I mounted this over a 32" garage to house door, with an 8ft ceiling.... fits perfect.  I haven't used it much yet, as it's still winter but the trial run seems great.
