No problems with operation, and as it's a universal charger, it's good value, since it an be used with batteries other than the one it was bought with.
This charger is a highly recommended item as it allows the battery to be charged off camera and at a faster, safe, rate. It adapts to various battery pin configurations due to the unique adjustable design. A big bonus is the ability to power the charger from mains or 12v DC so you can charge whilst driving! That adds usable value. Very happy with the charger and its well made and looks the part.
Very useful product, easy to set up.
