Pretty nice, but:
1. They don't ship worldwide.
2. I need a tach just for tuning (e.g. adjusting idle) and
diagnostics, and for that, my external counter seems to be enough for
my needs, just wanted it to better reflect the actual RPM.
3. For economy and legalities, I drive around 100Km/h (what
economy?...). Good enuff for me. No need for a tach usually, and don't
know where I'd stick a tach in my (desirably clean) dash?...

cheers,
