The battery connectors are easy to use because of light spring. The cigarette lighter adapter is very good because the battery is sometimes hard to reach in new cars.I tested the voltage with two different values (9.0 V and 17.0 V) and they were accurate compared to Fluke multimeter. Also the ohm scale was accurate. The probe draws ~60 mA which is very reasonable and doesn’t load the car battery too much. ### ⭐⭐⭐⭐⭐ Molto comodo *by on Reviewed in Italy 4 September 2022* Provato oggi. Sembra un ottimo prodotto.
