Small and very efficient blue light makes night vision, measure the voltage quickly and accurately, really like this product, installed in the console of the car is very useful.
The product may not calibrated, but with a digital multimeter is possible to calibrate from the trimpot.
I do not regret having ever purchased. A good option to check if the alternator arro eta working properly, knowing that the maximum voltage is 14.5 volts and the minimum is 13.8.
Buy without fear, cheap and efficient!
