This was very easy to wire up and I love the amount of information it gives so clearly.

Most of the other ones I was considering only displayed one thing at a time on a device that was more device and less screen. This one gives you a nice big display with everything you need to know.

Wiring it up was simple. It's a negative and a power wired to run the device, then one to each side of the shunt to get the reading. There's an optional 5th wire so that you can read the voltage from the starter battery (I did not wire this).

My install was for an RV and it seems to be made for a boat. For my RV mounting the back was needlessly large and the wire ran out of the back. To resolve I drilled out the side of the back and ran the wire out there, very easy to do. I mounted it by running the screw that's sticking out of the back through a small hole I punched in the carpeted wall part of my RV and fastened the plate that came with it onto the back. Easy easy.

This works very well in monitoring my RV batteries. Its nice to have percentage, hours remaining base off load and current load. Its helpful to me however seems expensive for what it provides. I could see this costing about $100 for the value it provides.
Would buy it again though as I cannot find a better alternative.
