On Training Wheels
I had one I thought was broken or put together incorrectly, so I recently bought another. When it too wouldn't sound chucked up in a drill in either direction, I thought it was also broken. But in another thread somewhere I saw where the tire actually spins the siren axle much faster than a drill would so I just checked against a tire and they both work. Why one works much better than the other remains a mystery to be solved.
