We installed a Sensomatic opener for our Garbage/Recycle drawer and it isn't funtioning very well.

Has anyone else here used one of these devices. You can just lightly push/pull or preferably bump the drawer with a knee and it will open.

We have it installed per the directions and it does work, just not very well. I don't think it senses the "bump" often. I am thinking we should move the sensor/arm back in the cabinet a tiny bit or add some sort of pad to the back of the drawer.

Looking for any advice or help from the experts here.

Thank!
