After the positive reviews, I was hopeful to have taken a good measure against the moles. It was initially the case. Immediately the entire garden was (> 900 sqm elongated plot) molehill-free. After 3 months, the mole seems to have unfortunately overcome his shyness. It would actually again worth a photo as new hill meanwhile towers 1 m away from the well-behaved piependem device. Too Bad.
