I needed them with external shunts but didn't pay attention when ordering so they sit unused. I've used models with an external shunt a few times to control battery power on my trolling motor, standalone desktop, etc. I had two complaints about this 2-3 years ago: 1) The light/set button was recessed and required a small screwdriver or the tip of a pen to click it, this has been fixed and now the button tip proud of the bezel. 2) The settings menu has an alarm setting as the first item and you have to hold the button down until the menu switches to what matters to me - resetting the watt-hour meter. I do this every night and it's annoying every time. I've got these alarm settings mixed up more times than I can count. I complained about it then, and I still do today. This is a pretty minor complaint.
