Most Helpful Review
"Not reliable at all, shows fake readings, no repair mode available as advertised and it doesn't work. No wonder why there is no warranty on this product. Worst charger don't buy it at all. It stopped working after 1 use. Literally smoke came out of the charger while I was charging a motorcycle battery. Don't even think to purchase it. Complete waste of money."
