Very loud and high quality

The horn adapts thin as well as thick handlebar. The switch can be mounted without tools.

The horn is very noisy and should be used in any case in ears close or close proximity of animals. There are two keys:
A) the intermittent tone is guaranteed perceived by motorists even in noisy environments.
B) high continuous whistle, but which is a little quieter and more what is for the bike path or in a loud environment less.
From me a strong buy recommendation.
