Must have item in households
I have been pleased with this battery tester so far. The item came packaged well and feels built to last. This is a great tool and must have item in households in my opinion. It's a simple way to check the health of your battery and other components such as the alternator. The cost of this item is probably what a garage would charge to do initial investigation on your charging system. Therefore after about 2 checks, you have made your money back. Time will tell how good this battery tester is, but for the time being I am pleased with this purchase.

Limited functionality...
Bought this to test a battery and to test for potential parasitic drain. Ended up using a diagnostic tool to do both which this unit could not.

Perfecto y fácil de usar
Muy buen producto,fácil de utilizar Lo he comprobado con el que me vendió la batería y marca prácticamente lo mismo y con el polímetro Hasta ahora funciona a la perfección,en mi familia hay varios vehículos y seguro estoy que le voy a sacar partido,te da una lectura clara y rapida Te da una idea perfecta de la vida que le queda a la bateria,la carga,prueba de arranque y si carga el alternador,lo recomiendo al 100% Le hubiera faltado una funda protectora,aun así le doy un 10

Molto buono.
Molto funzionale ha più funzioni, devi avere un minimo di conoscenza di parametri e unità di misura anche della elettricità in genere, in quel caso ti aiuta molto a fare diagnosi sullo stato della batteria e non solo. Ottimo e utilissimo perché a volte uno sostituisce una batteria che avrebbe bisogno solo di essere ricaricata.

Excelente
Aparelho cumpre com o prometido. De leitura fácil, veio muito bem embalado e seu envio foi rápido. Fiquei um pouquinho triste porque não tem a opção de língua portuguesa.

Semplice e funzionale!
Il tester fa ciò che deve e funziona molto bene. Ha diverse funzioni, tutte molto utili, per valutare al meglio lo stato della batteria e dell'alternatore della propria auto. Confrontato con un tester di qualità (e costo) ben maggiori, ho riscontrato parametri del tutto simili. Lo consiglio vivamente! In ultimo, spedizione Amazon sempre top!
