Hornady lock-n-load control panel primer slide sensor takes the guesswork out of reloading and alerts you when the primer doesn't properly align for your next stroke. Also counts strokes.
It works but it's not hassle free. For one thing clearance between this and the powder measure is very tight and if they hang up, you're toast; it disconnects your primer feed. The other thing is that it isn't stand alone, it has to have the control panel. So I give it just three stars.
Great device. I don’t have the Control panel this goes with, but I wired it a 12v LED light and buzzer that alerts me when the primers are getting low.
It's okay but you have to buy LNL control panel to use it. So I don't.
