The car marten repellent from ISOTRONIC made a very good impression in the test. The product prevents martens from chewing on car cables and also protects against annoying mice within a radius of up to 5 square metres. With a sound frequency of 12-23 kHz, this signal tone has an unpleasant effect on martens and mice, causing them to give the car a wide berth. No chemicals are used and the packaging in particular is very environmentally friendly, as care has been taken to ensure that no plastic is used in the packaging. The materials used are also of very good quality. The marten guard is installed by attaching it using cable ties or self-tapping screws and by clamping it to the car battery.
Advantages
✅Beautiful, environmentally friendly packaging method
✅Suitable for all cars
✅High-quality materials
✅Family-run, German company
Disadvantages
❌No customer hotline for any questions

*The maximum score is 100 points
The ISOTRONIC car marten repellent arrived for our test in a typical shipping box, so it was easy to open by removing the adhesive strip and was delivered undamaged.
The box contained the marten repellent, which was wrapped in paper, as well as detailed operating instructions in 9 languages. The packaging protects the product from scratches and dirt! In this case, the product was fully protected and the marten guard was therefore in perfect condition.
The packaging of the marten guard is completely recyclable.
The first impression of the marten guard is very good, as neither the product nor the packaging used was damaged.
After unpacking
Package contents and instructions
ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the pack complete and does the manufacturer make it as easy as possible for me to use the product straight away?

After unpacking, there were several individual items on the kitchen table. In addition to the car marten guard, our test included two metal screws, two cable ties and three cable clamps (to connect the cables to the battery), which are intended for attaching the marten guard to the car.
The manufacturer also provides an instruction manual, which explains the installation of the marten repellent in over 7 languages. During installation in particular, we noticed that it would have been nice if the manufacturer had included pictures of the installation in the instructions.
An e-mail address could be obtained by scanning a QR code on the packaging. The marten guard is guaranteed for over 2 years.
All in all, this is a very good way to send a product.

The ISOTRONIC car marten guard makes a very good visual impression in the test. In addition to its simple design, it has no manufacturing faults. The marten guard is made of plastic, which is common for products of this type.
The product impresses with its low weight and sturdy workmanship. The customer is supplied with high-quality protection against martens, which also emits visual signals in the form of a flashing LED when it emits an acoustic signal.
Unfortunately, we cannot find any information on sustainability , but the materials used appear to be of very high quality, which is why we assume that the product will have a long service life.
This is what our practical test showed
Does the manufacturer keep its advertising promises?
ℹ️ Our practical test is the most relevant and therefore the most important. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

| Fastening variants | Two mounting options | 100 points |
| Installation | Easy installation – also possible by non-professionals | 95 points |
| Total | 98 points |
*The maximum score is 100 points
We really enjoyed installing and using the ISOTRONIC marten repeller in our test. Installation is easy and can be carried out in two ways. The marten guard can either be attached with two self-tapping screws or with two cable ties . The materials are supplied for both variants.
Once the marten guard has been attached, the three cables are connected. There are two cables for the car battery and one which is connected to the respective terminal for the engine ignition . This means that the product is only activated when the ignition is switched off and the car is therefore at rest.
After installation, the customer can easily drive away all pesky martens. If the customer is not very familiar with the product, we recommend seeking advice from an expert at the garage!
In short, this is a very good product.
Price/performance ratio
and ratings from consumers
ℹ️ Finally, we look at how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also analyse consumer reviews and check whether the critical and positive reviews are actually justified.
| Criterion | Remark | Score achieved* |
|---|---|---|
| Price / performance ratio | Very good price-performance ratio | 95 points |
| Rating cut | No star ratings available | |
| Total | 95 points |
