The Energizer kit was received and installed around my apple tree in the back of our home, as a deterrent primarily against grey squirrels. I found the kit to be well made and pretty straightforward to install. A big key to success is to plan out well your installation ahead of time. The only negative I see is that the plastic stakes that the wire routes to and through tend to bend and curve when you tension the wire. They should be made more rigid in my view.
