I guess it's doing its job? They last a long time - you have to buy massive, thick batteries - but they last a long time (I've had them in there for almost 2 years now and they still work). The repeller emits a high frequency sound (intermittently) - I always put it near the engine in cold months in places where martens and other vermin might be present. So far (knock knock) no animal has made mischief in my car, if it's because of this repellent, who knows: )
I haven't got anything in the hood yet.

The fundamental problem is that the device is not ultrasonic i.e. using a frequency above the audibility limit (more than 20 kHz) but using a frequency of 12 kHz, which is within the audibility band of the human ear. The device can therefore only be used to repel martens from a cottage deep in the woods in the absence of the owner. However, anywhere else where people are present, the device is unusable. The frequency used is even listed in the basic description on the Alza website (In the parameters section, however, it is incorrectly referred to as an ultrasound device) Unfortunately, I did not notice this when ordering, because it did not occur to me that someone could seriously sell and offer a device operating at such a nonsensical frequency.
Nonsensical machine-translated instructions. From the English name of the device Marten-Free Mobile i.e. The mobile marten repeller was created Mobile phone without marten and in this spirit it then continues further.
The device does not meet the standards and should not be sold at all. It operates at a frequency audible to humans and has a volume of 85 db. Noise standards allow 40 to 65 db depending on the noise source at night. so the device cannot be left on in the car at night.

it's working so far. The martens don't get in the car even after a few months. We'll see what the battery life looks like in the winter.

product absolutely useless
it's audible even to humans and it's annoying
the plasic is on the cabinet and above it the mouse chews the polystyrene
and you still have to invest at least 150 CZK in batteries
I'll try a more expensive one but I doubt the effect of this nonsense
So I'm returning

Verified purchase - review from a price comparison website
The product meets expectations, after inserting the battery just turn on, nothing more, no short circuit threatens.
