We have, as indicated, engraved with an old broomstick and a hammer 4 deep holes in the unfrozen ground and in the Mole Schreck installed. The first is nevertheless already canceled by the style, because we have probably not pressed gently genuzg. Well, that may be our fault, but a shame that the article is so sensitive. After we had 2 days of sun they need to be recharged enough despite cold temperatures. On Off course they were also. The mole can safely but unfortunately by not discourage (and that although we have installed a fright at each of the four corners of the 700m² large garden) and digs diligently his pile. One even remotely about 1m from a fright. We are very disappointed and will claim the goods.
