has any one used one? for street or stunting?

i had a longer post but it would not go through.

 

ver heard of a thumb break
what is one
and why would you want one over a regular lever?

 

sorry, had a more specific post but it failed. it goes on the left side of your bars and replaces your rear foot brake. so instead of your right foot working the the rear brake, your left thumb does it.

i dont li ke useing my right foot for braking and always end up locking the rear tire up. (steel plate in my ankle might have somthing to do with it, that or i am just bad at it.)
