Seems to work well enough for my needs, but there are a few minor things I want to mention. 1) The color of the front panel is not black (like the photo). It's more of a cardboard color and doesn't feel like a protective sticker that you can easily remove. So it's not as "beautiful" as I was hoping. 2) The front panel is not overlapped except for the left and right screw holes. So if you cut out a space in a back box to mount a gauge, it doesn't look professional. 3) Just note that a voltage somewhere north of 12.8V is expected before showing 100%. If the batteries are charged or floating, this is not a problem. But when they are full and the charger is idle, it will NOT show 100%.
