Is there hearing impaired Marder? - Maybe not

If it actually should be hard of hearing Marder, then I have such a rare specimen in my underground and the purchased equipment can not help it that the raccoon did not care if the part will beep or not. Then I apologize for the award of a single star. If my Marder should not be hard of hearing (which is at least in the realm of possibility), then the device is good simply do nothing. I have the part in front of my car hung directly into the underground car park (... and it beeps ... because of the human ear does not hear ... of course you can hear it ...) and there is no day (or any night ) took the cattle and was back and has done to my car aerial to create. From because of the thing sells Marder ... it just brought nothing. Simply a waste of money. I've got it now with the enclosed cable ties in the engine compartment moored (what worked without any problems). Let's see if the cattle no longer distributed at least be Vespers in my car. If now should be quiet, I will complete my review of course and also awarded more stars. At the moment I'm just disappointed with the part.

UPDATE:
After a few weeks of the unit in the engine compartment, I would like to improve my rating 4 stars after all. Bought together with a marten carpet (under the car) ... even at Amazon ... the raccoon has at least no longer holed up in my engine room. Since washing the engine (prior to installation of the device in the car) no traces of cattle are more visible in the engine compartment. Whether this is now on the device or on the carpet Marder, of course I can not say. But the combination definitely helps. So I revise my opinion and say that the unit helps the engine compartment when it depends only in the garage (as promised), the part is of no use. Unfortunately, holding the raccoon but still not stop them from to verlustieren to my antenna. But the fun I've spoiled him with an aluminum antenna also now :-)
