Review on KNACRO Two Way Solenoid Control Universal by Junrey Jewel

No instructions. So I had to set it up and test it on the bench. What good have I done? Because the current you want to run through the switch is actually powering the device. The output is the only thing passed. Exit+ is always on. So the current goes into the voltage terminal and goes straight to the output + terminal, and the output is the only thing that is turned on and off by the timer. I had to toggle the + loop on and off. Didn't do it. But once you figure out the other setting and how it works, it's a good little timer. Just didn't work for my situation, what better descriptions and instructions would tell me about that.
