No raccoons on my roof.
Item reviewed:The Guardian™
I purchased the Guardian (AC adapter included) from Good Life in June 2008, as I was having a problem with incessant squirrels on the roof of my mobile home. However for various reasons, including that I did not find the instructions easy to follow, I did not end up using the machine at that time.
A week ago, a number of raccoons started spending the night marauding up and down my trailer roof feasting on a large crop of apples on a tree up there this year. The first night this happened, I was awake till 5am, despite hosing the roof down with an intense water jet at intervals.
The following day, I dug out my Guardian, and got it set up. For the last three nights, no raccoons on my roof. I am delighted with the results from using this product.
