Is it louder than the old school way of an empty water bottle?

My grandson loves it. Its loud!!!!!

can i mount this on my unicycle?

i don't think you can hook it on a unicycle. no where to hook it.

Does this work on a bike with a gear system?

I would think it might however we put it on our grandsons bike and it is just a single speed. It would depend on if your sproket got very big. It rubs on the spokes of the back wheel is how ot works. It can be put on either side so I might tend to believe it would.

can you buy just replacement cards? My son loves this, but we've had it 2 days and he's already managed to break 1 card and lose another.

Yes, google replacement cards for turbo exhaust. $20.00 a set

Price and functionality

Don’t buy , cheap plastic. HIGHLY OVERPRICED for the product. Very disappointed. A clothes pin works better. Should have gotten a refund. $56.00 for nothing. Grandson was disappointed.

Happy with purchase /Recommended

Purchased for child who loves this , the neighbourhood sure know when this is in use. Has a card that inserts with option to easily take out if not in the mood for some noise . Haven’t had any issues with it falling off. Keeps the Jnr rev head happy. Would make a cool gift. A modern take on the good old pegs and cardboard in the spokes.
