This mole fright is simply the best I've ever bought. And I've already bought some with solar technology at discounters and seen. All were inferior, defective or soon IMMEDIATELY! However, this part has a very different quality standard and high quality finish. I have Davo spared to buy a mole repellent with batteries, because it seemed too expensive for me but I was informed of another. Already Kurza to be exhibiting, the small animal, however twisted in my front yard (Grrrrr ...) because there was the mole fright too far away. Hardly left the batteries after six months (!!!!) to, my friend came again to the back and nibbled on three Tujas. Even the front it has a tree for 350, - Euro nibbled at the roots well and he seems beyond redemption! That's why I'm considering to NOW a second mole fright for the future! Anyway, I'm excited because it's the only mole fright of work in the long term, a super long battery life (despite winter hell!) Had more than 9 months, even if the large batteries cost a few Euros. He hardly falls to (as opposed to most ugly solar parts) and is super. So buy !!!! :-)
