"I did have one that I had to work on so that the screws would grab the vent. Turns out one of the six vents was too short for the pre-drilled holes, so I had to lower the screws. It was fine after that."

"Yes, my order was received promptly & I had no problems with the installation.
I noticed that you improved the product by adding some new markings on the exterior. That certainly would have come in handy if I had to cut the bottom for a differently sloped roof. Lucky for me I didn't have to do that.
I'd highly recommend the Critter Quitter® to anyone else."
