We began to be kept awake by that scourge of French housing, the Glis Glis. Night after night, we or our guests were kept awake into the small hours of the morning by the pests running around and squeaking. We heard about the success of the Green Shield small commercial units against these animals, and decided to try them, so we bought four units. After a couple of weeks, the noise had not reduced, so I called Green Shield to see what should be done. They advised that we should use only two units, kept further apart, so that there is no overlap in the magnetic fields, and after following their instructions, and to our relief, within days, the Glis Glis went quiet, and there is still no noise.
Many thanks for these amazing units, and for the excellent customer service.
