Title: Sonic gopher repellant doesn't repel gophers
Review: I do not recommend this product. It has been in the ground for 2 or 3 weeks and fresh gopher mounds are appearing within 10 feet of the spike in the ground. The spikes continue to emit annoying noises (at least to humans!) but they do not appear to repel gophers.
