won't last

Worked good while it lasted, which was only about a year. Then had electronic problems, became erratic, then non-functional.

Nice pricepoint, and nice charger.

Great form and function. Batteries could be a bit higher capacity (1 star off), but for the money, great for spares, and I love the charger!
