Here is the latest review on Home Depot for our large sized unit. 5 stars. Note the record time comment. Critter Quitters are designed to be installed quickly with a quick cut and 4 screws. Below is the review posted on Sept 12.
Luckily my son in law was here on vacation, and he installed both Critter Quitters for me in record time. Good product and a great son in law! I’m very pleased. The squirrels not so much.
