This is value for money - good build quality at a good price. The schematic (viewed from the side) is helpful and the size of the part is spot on in my opinion. It's a little difficult to read on the display that you're off axis. So be careful when setting it up. I would buy two more of these (for my boat and my RV) if they added Bluetooth and an iPhone display app with data logging. There are such products, but they cost $200 or more.
