PROBLEM: With the new memory cards the digital cameras take HUNDREDS of pictures which is great .... until the message "Low Battery"! This time I remembered four days before my son's wedding that I need a spare battery! Ran to the mall, to the electronics stores, but nobody had it. The answer was " contact the manufacturer". There was no time for that, except AMAZON.COM. Two days later arrived to my house! That's service! Of course I was able to take thousands of pictures and save my son's wedding!

SOLUTION:
Positive
