Honk! Honk!! Honk!!!

Works fine, as it must! I bought this to fix on my mother-in-law's walker so she can clear the path as she walks (we have a lot of pets at home!) This is of good quality and a good buy!

Excellent product

It is loud and very useful for night cycling purposes

Worth it!

A definite recommend to anyone who wants to be heard loud enough on the road. It is easy to install on the bike. Can be used as a novelty item on your motorcycle or at home too. The horn is very loud and does make you stand apart. Build quality is sturdy and I use it extensively and it is still as good as new. For this cost, it is a definite buy hands down.

Not durable and less effective

I thinl the bulb efficiency needs to be improved and more strong material has to be used

Thank you 

other uses... not limits!

I bought this, for my 82 year old mother, who suffered a stroke some nine months back and lost her ability to speak an use her right hand. The horn, which she is so familiar with because it is truly retro, is he call bell... to call the attendant or me when she needs assistance. she's not about to ride a bicycle any time soon, but this is her connection to the world outside her room... i love it :)

Good One

Good Horn. I am using it on my cycle and it serves the purpose. Since you dont see this kind of horns in India nowadays, it attracts people. No problem , except the rubber became bit loose, are faced by me.

Bike Horn

sound of this product is good, overall is good but the big reason behind 2 stars is its back rubber part which is very loose in fitting, it drop somewhere when my son was riding his bicycle and without that black rubber blower this horn is useless.

Dear Mohan,
We are sorry for your less than satisfactory experience with the horn and thank you for highlighting the issue. The clip bolts, when tightened rigidly will secure the tube firmly with absolutely no movement. If the rubber seems loose its probably one odd product which you can get it exchanged. This review will really help us to feed the R&D team, to help them improve the product. For any further query, I am available. 
Good buy

My grandson 10 years old was thrilled to get it. He created lot of noise in the house. Later fitted on his bike and rode around the complex.
