Excellent product September 27, 2023 Reviewer: Gordon Estabrook from Denville, NJ United States   I use my batteries all the time and need to have them available quickly.  This charger gives me the option to charge and carry multiple batteries during my work day. It also tells you the power levels on the batteries.  I like that feature Was this review helpful to you?

Best charger September 23, 2023 Reviewer: Mark A from Glenolden, PA United States   I love this charger. It lets you know what condition your battery is in along with other information. It is the fastest charger I've ever owned. Was this review helpful to you?

Decent charger September 17, 2023 Reviewer: Danail Ochkov from Cottonwood, AZ United States   The charger works as intended and charges the batteries well.  However I am not sure how accurate of a device it is as it gives me different and sometimes conflicting information.  Fo example, I get different resistance values every time I insert the same battery.  Sometimes it will display "Poor" for a particular battery and if I change the slot and it registers lower resistance it will display "Good" and will charge the battery.  So, all in all it is better than my cheap ($15) charger since it is able to charge a large variety of batteries and it gives you information about the charge of a particular battery but probably it's not much of a precision device.
