## Customer Reviews

### ⭐⭐⭐⭐⭐ Iconic Italian horn
*by S***S on 15 June 2024*

Love this horn had one fitted to my fiat 500.

### ⭐⭐⭐ exterior corrodes could/ should be engineered better.
*by S***S on 30 June 2018*

Reasonably loud and a noticeably different tone to original horns although could be louder. Have had to take it apart to dry lube the impellers to keep it working after just a couple of months, note contacts are on the bottom and connectors/ wires end up adding to the height loosing some of the compactness, exterior corrodes could/ should be engineered better.

### ⭐ Not great
*by M***. on 9 March 2019*

Sounds like a normal weak horn before the compressor kicks in. It's either faulty or rubbish.
