[EX Q]: This does the job, and it works well. The only problem is that if you use your phone after it's fully charged, which takes quite a while, it'll kill this power supply pretty quick. There was also an internal short in my unit after several months, leading me to believe I got a lemon. As others have noted, their customer service is excellent, but they will not honor warranty. What we ended up doing at our local electronics store for a replacement charger wasn't bad either.
[EX A]: Bad review

[EX Q]: My husband bought both of these toys from Toys r us.
[EX A]: Bad review

[EX Q]: I can't see how or why anyone could find this book to be funny, especially when it's packed with so many grammatical and vocabulary errors. On almost every page there's a run-on sentence which makes it difficult for the reader to understand what's being said. Even worse is the fact that a lot of them can (and do!) make absolutely no sense whatsoever.
[EX A]:
Bad review
