err...if you think paying US$18 + US$15(shipping) just for that readout (which you may not even look at it during astro) is worth it, then I got nothing to say lor.
The one found in shops here is SGD$8-$9 at most. While it has no readout, it function the same. The sligthly more expensive ones even have cute LEDS on it...
1stly IMHO I don't think with a real digital voltmeter, it will be so cheap and not sure if the space is big enough to get all the electronics in it.
2ndly, it indicated with the word simulated display and also with letters HML in it. My guess this is not a true digital voltmeter but those typically uses diode to create to volt meter effect which 12V = L, 12.6V = M and > 13.2V = H. In some cigi adapter it uses red, amber and green LEDs to do the job. Well I may be wrong.
Agreed with VinSnr, one hardly look at the reading, the only time may be before one start the car. I do have a pc with the LED indicators, when I installed in my car, never look at it during driving. If the alternator is working it will be > 13.2V. If the alternator is bad, you can start your car the next time. The only good thing about the indicator is before you start the car, red LED or no LED light up, you are in trouble. And I've never encounter this condition.
So is it worth all the extra $$ for something just for show? VinSnr fully agreed with you, mine is a white elephant now.
