Our 1800qm plot I first supplied with 2 of these low-frequency-Brummer, and in a radius of about 20m can now be seen no more Mole - but makes an area of approximately 320sqm and not the optimistic advertised "up to 1000sqm" per piece - 1x point deduction. Pleasant against the solar equipment is the dull, little intrusive sound, just a mechanical shaking instead of high frequency (annoying) peep other models. Anyone who wants to get rid of moles in front of his window, knows to appreciate this. Price: Quite high, even for stainless steel, hence the 2 point deduction in the standings.
