This drum key works just as fine as any other drum key, so for this price it seems to be a done deal! Why would you buy any other one?
The metal is hard enough to not wear out, and the handle is big enough to put some force on it.
I also like to tune the drums by ear instead of using the automatic tuners, because they will not get it the way I want it tuned.
So, I think it's as good as they get, and really cheap!
