long averaging time
on December 13, 2014
The update rate seems slow, so it's difficult (impossible?) to know your RPM at a particular instant. The averaging time seems to be a few seconds.
Otherwise, it is exactly as described. It's a somewhat functional tachometer. It's rather small, but has been installed on my raceboat for almost two years. So it's rugged and durable, as it's lived outdoors this entire time, survived many races and even a couple of crashes (and occasionally gotten wet). The LCD is somewhat recessed in the housing as you can see, so you have to look at it pretty much straight-on.
The main detriment is the averaging time / update rate, which makes it not very practical.
