Excellent and works well! It's a blue backlit LCD, not LED as in the description, so it's BETTER. The actual digits are large and much better than the BG image. The refresh rate seems slow at 2~3 secs but doesn't matter, an excellent meter for those of us who want to wire one in. Seems to keep it's settings during a power-off.
For the money this kWhr meter is fantastic! Just 2 issues: no boxes are recommended for that snap in lid, the ones sold here are either too large or too small, and the upgrade connector is backwards. Note in the picture that it is designed to have the wires connect from over the board so the snap in lid works, but the capacitor blocks the middle connections. To use 12G wires I had to unsolder and reverse the connector, use a larger box, and all is working great.
