Nice sales video of these guys doing the removal and install.

I didn't like seeing only half the shingle getting nailed, never seen that, sure save less arm movement, faster install, but big winds get under any area of looseness, as the roof is an airfoil, and has faster lower pressure air as it passes over the 'hill' airfoil. You get fast enough winds, and it will pull up on the roofing from underneath, and if the wind gets fast enough pull up, and that nail head will pull thru the asphalt shingle. And his area of looseness has a pattern of a long area that can let a large area get pulled upward with faster and faster winds.
I've had much experience with wind. A small tornado about 1/2 mile to the north, but ground wind velocity removed those final hip shingle on the plastic vent. That is the Achilles failure to winds above 60MPH from my experience. That final end that is nailed and sealed, only has a single layer before the roofing nail's head will pull thru, then it blows off as big pieces as they have glued themselves from the self stick. That roof was done in 2011, and 2014 I had that failure. Then in 2020 we had a huge derecho that started in Nebraska, and did damage though Ohio (if I recall), that took the same roof hip shingles off the same roof, as well 3 others house and another garage roof. And that opens to roof to the elements, and that produced 2 inches of rain in 35 minutes. Part of the house flooded. Worse, it got under the hardwood floor, and caused it to ripple up. So NO I do not like these roof vents. They go by the name of Mongoose, or Cobra (same design, odd story). And they really do not let the thermally hot air out as there's too much fine mesh restriction to keep the bugs out, as well hard blowing rain making it up the corrugated holes (looks exactly like corrugated cardboard in several layers). These holes just won't let the very hot air out fast enough from my experience. They are better then nothing.
