Query: Can't Recomment Hella Supertones

I've installed Hella Supertones (made in Germany)on 2 previous cars and loved the results. The ones I just had installed are made in India and both the sound quality and loudness are greatly inferior to earlier Hellas. I'm unable to install them myself, so I had a very reputable VW shop install them on my 2010 GTI. Took 2.5 hrs labor at $75/hr. Wish I'd never bought the darn things. The Hella spin is that they're 7 times as loud as most stock horns. They might be almost twice as loud, but the frequency is lower and not attention getting. Save your money- these do nothing to add to safety.
