The items arrived well protected by the packaging. They make a range of noises of varying types, some of which at close quarters make your ears very uncomfortable. They are very suitable for the intended purpose and would work equally well on a bicycle or disability scooter. The quality is very good - they are protectively waterproofed with a silicone skin. I was not able to work out how to change the battery. It takes quite a bit of hand strength to push in the horn button.

Received product quickly as described. Thank you!
