I finally just let the timer sit to see how long and if they would open. They did but not even close to what I set. I think the thing to know is, don't plan on them popping when you need them. Test them first by the lines provided to see how long 1 mark takes. It's not a true hour. At least not on those I have. But, since this is my second review it seemed important to share that, they do work, just not like others I've owned. This applies to the 2 and the 1 slot Pawise feeders.
