I got these for my jawbone headset. Many had said they work great. but for the life of me i cant figure out how you get them to work short of superglue and even then they are too quiet to hear so i guess they work on the jabra they are designed for but not the jawbone.

I've been a longtime fan of Mercedes and own most of her Valdemar series. So, of course, I picked this book up at my local store. After wrestling through 50 pages, I gave up! I plan to sell it back to my local store ASAP- this is nothing better than a paperweight in my bookshelves. The worst part is, my boyfriend picked it up and tried reading it. Now he thinks that this is a good example of her work!

Genuinely funny and moving - exceptional film.This is an exceptional film that shows that no matter what life throws at you, the human spirit can survive and make a comeback. I love films that show you the inner strength of the human spirit and peoples faith. The film is genuinely affecting - it is funny, very moving and it looks exceptional on a big screen. Most of all though this film entertains without resorting to cliches and melodrama. Diane Lane is exceptional and deserves Oscar recognition for creating such a three dimensional and believable heroine. The acting from everyone is first rate and the direction is fresh and infectious. An exceptional film!
