★☆☆☆☆
battery almost dead after just 3 months
I really like using this product. And when I received it 3 months ago the battery would last about 2 weeks. However 2 weeks is now down to 2 days. At this rate I suspected it will be a paperweight before I know it. I understand that batteries have a limited lifespan, but a quarter of a year is much to short.
