Query: NOt as reviewed by others

The reviews were VERY favorable for this drum key. Burt it does not work as advertised.The key is fine, but the extra expense for the tension dial was not worth it - this key does not work on ANY of my tom toms on three drum sets - because it is not nearly sensitive enough. It needs lots of tension to even start to register. Maybe this works for tightly tuned marching drums, but it did not work AT ALL on my drum sets.I am very disappointed, as the reviews were so positive that I bought it. Too good to be true.
