Holy Vent Kit! The sticky tape that comes with the unit is horrendous! It sticks to your hand, the wall & pierces so easily. I just ended up stuffing the thick foam in the window frame and that worked great.
The unit itself - AWESOME! Within an hour went from 87 F down to 78 F. 
Yes it is noisy, but not unbearably so, & is worth it to have a cool house.
I used this unit in my front room with a high cathedral ceiling.
