Before, my wife would forbid me from driving faster than 85 mph. But after having installed the CarTuner I can cruise at 120 mph and she still look dreamily out of the window. She says she is completely relaxed and headache free. Fantastic!

I’m totally thrilled by the CarTuner. I drive a lot more relaxed and have the impression that I need less diesel.
– Angelika P., Biederthal (F)
The CarTuner is the best thing I’ve bought lately. My children are not naughty in the car and of course they do not battle it out on the back seat. That has always been very annoying. But what I like best is that my tank of gas lasts longer. Doing my budget very good!

Dear Mr. Neubersch, may it be that the CarTuner also has an effect on the static charge? Anyway, it does not happen to me recently that I get a shock when I touch my car. And the funniest thing is that my fuel consumption has reduced from 9.6 l/100km (24mpg) to 7.5 l/100km (31mpg). I never would have thought it possible. I ordered your product because I only wanted to do something about electrosmog in the car, because my wife has always suffered. But that’s over now. Much Obliged!

Dear Richard, as you know, I often fell asleep in the car for a few seconds, even if I had only short trips and was fully rested. When you told me that this had to do with electrosmog, I did not believe you. Actually, I only let you install the CarTuner because you were so confident that it would help and that I thought I would give it back to you soon because it does not work. But I was wrong, since I have it, it has not happened again, no matter how long my journeys are. So, in retrospect, I thank you from my heart, also especially because I have less gasoline costs. I guess it’s a good 10 to 15%.

Thank you both for sending the car harmoniser so quickly to us in France.
I did the 240km round trip to Toulouse airport yesterday & definitely noticed a difference.
I didn't fall asleep on the journey there (as a passenger!) & felt much more awake driving home having picked up my parents.
And a big blind test was the fact that my father (who always falls asleep within 10 minutes of getting in a car & knew nothing of the harmoniser) "felt sleepy when he left the airport but then woke up on the journey"
