Review: BUY THIS - Absolutely would recommend works great Im so glad I don't have to go to the parts store to test my battery, starter, and alternator anymore 😅
Review: Tester di uso intuitivo e ben fatto come di consueto per questo marchio, da me conosciuto per un precedente acquisto. Testato finora su una decina di accumulatori ha fornito risultati coerenti con l’età e lo stato effettivo: non perde un colpo anche riprovando più volte, direi non ha nulla da invidiare a tester professionali (c’è anche la versione che stampa i risultati su carta termica!). Difetti nessuno per ora, forse la confezione in plastica trasparente espone il display a qualche potenziale danno, dato l’imballo di carta un po’ misero. Una chiara raccomandazione d’acquisto, desertcart come sempre puntuale nelle consegne!
