[EX Q]: The light weight case didn't really hold a charge, I bought 2, which was great becuse we have multiple phones, and one of the batteries still doesn't work out after only 2 months. But for the price, you can buy another.
[EX A]: Good Review

[EX Q]: Don't waste your money on this item. As soon as I plugged in the charger, it would not work anymore. Now It will cost me more to return than I paid for it. So here we go again. Only good thing about Amazon is that the returns are free. Do yourself a favor and don't buy this. You might as well spend $30 at Walmart or Target because you're going to get some junk right out of there. Just be careful when you take it out. You're gonna need a box cutter.
[EX A]: Bad review

[EX Q]: I gave this product one star because of only the fact that my dog liked it. However, he is not interested in other 'treats'. He will still carry these things around for a couple minutes and occasionally sniff them once or twice, but they are really just "food dust" -- something else to chew on. No reward associated with those small pieces when you first give it to them.
