the equipment we have for 2 years in the vegetable garden in use. Mole and Vole (which both are here in vast quantities) avoiding the effective range - at least within a radius of 5 to 8 m - significantly. so I feel the unit to be very helpful. However, strike our device in strong rain, it runs full of water and has to be dismantled and then dried. then it works again. also turned-over plastic bags are of little use against the wet, I suspect that the water may be "sucked" even from the ground. once the device is silent, our angry digger rush to work immediately and buried it under a huge mound of earth clever.
