They are coming in a lot faster these days as our Home Depot sales are way up. I would think the virus has something to do with that. Anyway, this is for the large size Critter Quitter. 5 Stars. And to answer the question, Critter Quitters are made to last decades and they have minimal issues with animal attack as they don’t provide anything beneficial for them. They pretty much leave them alone. Here is the review done July 1.
The Critter Quitter slipped right over the existing vent stub and was promptly secured with the screws supplied. Only time will determine the true effectiveness and longevity of the product.
