Has anyone successfully installed one of these?

                      it appears that nobody has any personal experience with these new devices, or they are not prepared to share their experience with them. So, how do you practically ensure a three degree slope downwards to the outside when drilling the hole for the duct tube? If the tube slopes at more than three degrees the outer flexible collar will not fit snugly up against the outside wall.
