I installed a clicker I've had for some time, I believe it's called a Clickety Klick. It seemed to work well at first, but now I don't hear it click while pulling back to anchor. Instead, if I let down, ever so slightly, then it clicks. This is reeking havoc with my rhythm and concentration. Is there such a thing as a defective clicker ? I mean it seems like too simple a devise to be defective.
