PROBLEM: i did not enjoy this book at all. it was pretty boring. the only part of my interest in reading and finishing is finishing what we started. unfortunately, it didn't come together for me.

SOLUTION: Bad review

PROBLEM: I loved the product when it arrived, but within 2 weeks of using it, one side is completely dead and I've barely used it. Also, my old adapter, while being much more compact, didn't get hot as soon as it's plugged in. It may just be defective, or maybe this model was designed to break fairly quickly. Either way I'm disappointed. :(

SOLUTION: Bad review

PROBLEM: I ordered the one with two batteries, so when my other battery died while traveling and was in need of recharging, this is what i used for backup. It charges quickly - quick enough that you can be sure you've charged it fully before leaving on a trip. Charging time appears to take about 1 1/4 hours from zero. The charger shuts off automatically after 7 hours, or until you turn it back on.

SOLUTION:
Good Review
