This horn is of course adorable, and was a hit with my 2.5 year old son for his bike. It is unique looking and fun. It is also very loud, which is good for a bike horn since the purpose is to warn people you are coming. I took off one star because looking at the design, I fear this horn might not last long if the bike has a couple spills and lands on the horn, or if my son pulls on the head sideways. The rubber head is attached to a narrow plastic mounting bracket, and bending the head puts stress on the seam (glue?). I fear a tear in the seam or rubber could not be repaired to make it function (squeak) again. So we will see, time and regular use will tell.
