Repeller Battery

Solar and / or battery operated mole / gopher repellents-Does it really work?
The kind that stick on the ground that emits a frequency low or vibration. My garden is eaten with mole tunnels. Anyone with experience in using these devices?
Teri, there are two degrees of them. One with a plastic tube (said in the package is good for the 5,000 square meters and a metal that is good for 10-11,000 square feet We sold out both in the L & G center and customers say the plastic back and did not work and other customers with metal back for more. So we stopped selling the plastic because we want to sell something you do not know satisfactorally. We are selling the metal, and although they are expensive, they do get rid of most of subterranean rodents. The batteries last about 5 months.
