Basically, it does what I bought it for, well. Backlight is very bright. (You can turn it off.) Shunt is wired for current usage (my choice) and looks good. Screen has a lousy viewing angle. Straight on or nothing. I have it installed quite low, so that’s inconvenient. Mounting the shunt is a challenge, since there’s nothing built-in for it. There’s a smaller one available that I would have preferred for this reason, but I found it too late. No insulation on the shunt.
