Product review (4 stars): Bad instructions but it works fine.
I agree with the other reviews, the instructions are basically useless. I skipped using the jumper wire since my old timer didn't have one. No wonder the timer wasn't running, haha. When it's working you can see the gear spin through the clear cover. I noticed on mine that the jumper wire will slip over the pin you want to use with a little pressure. My instructions say continuous timing is pin 1 so that's what I'm using. So far it's working fine.
