ISOTRONIC® Solar Mole Scarer, Effective Vibrasonic Deterrent against Mole, Mouse, Rat, Ant, Vole, Snake - High Frequency Outdoor Repeller - Pack of 3 Pcs.

I can't really call these mole scarers as the mole seems to quite like them.No change in mole activity since placing them in the garden. Plenty of mole hills appear every night, most very close to the "scarer".Not sure what frequency these should be at, but they are definitely in the human audible range with a clearly heard beep every 40 seconds.Think I'd be better off sitting in the garden with a hammer playing my own version of "Whack-a-Mole".

After a year in the Welsh rain and wind one of the three repellers has gone cloudy in the glass so you cann't see the solar panel. The other two are still working fine. Asked ISOTRONIC if there was anything I could do to fix it and they immediately sent me another box (3) of repellers. One way or another, those voles are in for a noisy summer. Thanks a lot to ISOTRONIC, great service and well done.

Used this unit for some months now and no sign of moles again. Note that you do not get 3 units as Amazon has messed up. According to the seller there is only one. I’m waiting to hear back whether I will get 2 more units as per the advert.

Put in garden to deter moles. Full of condensation next morning,one still working. Two making intermittent rattling noises. Dried them out in airing cuburd. Put back out full of condensation next day none working. Not the quality of product made in Germany I would expect.
