Here is a picture of 5 bulk boxes of XL units going to Critter Control of North Central Indiana, and to Cedar Roofing outside of Chicago. We usually don’t get bulk orders for XL units, but they use these larger vents up north.
"So far we are very pleased that the squirrels are no longer feasting on the lead vent pipes. The installation went well the only thing that was a little disappointing was the Critter Quitter® was not long enough to meet up with the roof. Apparently the vent pipes were a little longer then normal and the roofer that installed them did not want to try cutting them down. Since they are not seen from the front we are not concerned as long as the squirrels leave them alone we are happy. If we had to replace them we would like them to be a little longer but so far so good. It is a great product and was a quick fix to what could have been a costly repair. "

"I installed them right away. It took me a minute to realize you had already precut them for me! My biggest issue was I was using a manual screwdriver and I wanted to tighten real well but my hands were sweating. Other than that I was really happy with your product!"
