Funtioniert easily - very nice contact with the manufacturer

After parking in a foreign Marder station, our "home Marder" the Überzegung was he to run amok in the engine compartment on Gummigeraffel.
After repair it took none 2 weeks because the same sites were to determine exactly the same damage. Burned again money for the repair.
Then came the decision, it must be found a solution. After a lot of reading of useless advice, came only ultrasound or electricity in question. The decision was for me at the end but clearly towards power. Why? This is followed by a mammal can not get used. An unpleasant sounds probably more. So: power always helps! Good old fence concept.

Important to me was a simple installation and removal, due to frequent car changes, absolute reliability.
The advantage of the system 737 is that the sensor, which senses the opening of the hood, operates without contact. It must be screwed no push switch somewhere.
When closing the hood, you will be informed by short beep that the system is functional.

Because actually the only remaining question is whether the part of the job.
Answer: Yes. Silk months marten free. What more do you want ...

A tiny drawback: The first use I was at one point describing a little confused and thought it was a mistake, either with me or the device. A quick call on a Saturday at the manufacturer in Switzerland (the German sales had only the AB on) was explained to me in a friendly Schwizer Dütsch where my mistake was and a few minutes later the thing ran. Very nice contact. Thanks for the help.
The device is not one of the best on the market. But who buys cheap, buys twice. This is done here only if you want auststatten a second vehicle.
