The product was received in terrible condition, the packaging was damaged, and there was no horn clamp on the handlebars. I had to wrap it around the handlebars with rubber bands. At least it works.

Strong horn in sound, but it does not have 4 different sounds, it has different levels of intensity from low to high.

What came into my hands was exactly as shown in the picture. The button is discreetly placed wherever it suits you, and the intensity is sufficient to make you feel like you're riding a motorcycle. It doesn't have different sounds, but it has different levels of intensity. I highly recommend it.

It has a loud enough sound but its reaction to treh button is not accurate. It rings longer than expected, I finally installed a traditional bell on my bicycle after this one.
All in all, if you ride in the street and among cars, it's the correct choice.
