[EX Q]: I ordered these in 2 colors....blue and purple, both of which arrived defective. The right ear piece only functioned sporadically without any input from my phone at all. Amazon is sending me a replacement pair but the same problem with second pair. Very disappointed in this product for quality control, however they were pretty great when working right. Will give it one more shot before resubmitting review. Don't buy unless you want to waste time trying out multiple pairs.
[EX A]: Bad review

[EX Q]: I was very excited to find out this book had been made into a film and I'm not too keen on the book. The movie adaptation has me worried. As you can probably tell it doesn't quite measure up to the book, some of my favorite elements were changed so as not to take away from it's story such is all love stories have to do. It's still a cute movie, but not really what I expected. Worth the watch though, just don't expect a classic story.
[EX A]: Good Review

[EX Q]: We had bought another product that did not work with the new Kindle and were surprised at how helpful you were. You answered so many questions about our product it saved us from returning it. So we ordered this charger which works perfectly for what we wanted. No problems now to report on your products, we love them. Thanks all in advance. Carol B. Kleczka Oregon
