Luna cycles Watt meter
I'm not exactly sure what I was expecting when I purchased this meter. It does exactly what it was advertised to do, measure energy delivered. It seems well made and is very accurate. That being said, for my purpose, as a casual ebiker, it is an un-necessary add on. The biggest draw back is it's always on and consumes a minimal amount of juice as long as it's connected. It's hard to read in the direct sun, and cycles thru the info too fast for me to read. I would not discourage anyone else from purchasing, I just don't feel it's the best money ever spent.
