"I priced the same size battery at a "Radio" store and it was $4.95. Since the using device cost that much, I didn't want to spend $15 on batteries. I discovered Batteries in a Flash on the net and found a "10 pack" for $4.95. They shipped the next day and I received them the third day. They work fine, at a tenth of the cost, and I have spares! I'll check with Batteries in a Flash every time I need a battery!"
