Question: I bought these. After two uses (the first being a french vanilla cake, and the second fudge brownies), they stained from the brownie batter and will not come clean. I figured these would be better quality, since they ARE kitchen aid.

Answer: Negative


Question: My Nomad Jukebox Zen Xtra 40GB only worked for 6 months. I no longer have any sound and the battery doesn't charge. When I called customer service I was given the excuse that it wasn't supposed to be used in the gym. As you all know it is marketed to fulfill your portable music needs. If you can't use it in the gym then it is not truly portable. I know many people who use their ipods in the gym and have had no problems for years. This product has fallen far below my expectations. It is not worth the $300, not to mention the fact that it only has a 90 day warranty. Can you trust a product that is only guaranteed to work for 3 months? No.

Answer: Negative


Question: Normally, I read contemporaries but this series drew me in. Ayla struggles to live when ice sheets were retreating from Europe. She's raised by Clan, people who communicate with body language more than vocals, and makes many mistakes on her way to adulthood. Jean Auel's research at times intrudes but mostly this is a story that completely transports the reader to a long ago time where you root for the heroine and feel the fear and trauma along with her. My bookshelves are few but this series has designated space because I revisit favorite scenes often.

Answer:
Positive
