Question: Excellent product. I was having difficulty hearing and also getting a comfottable fit with the included ear hook that came with my Jabra JX-10 Series II Bluetooth headset. I removed the hook and attached one of the 6 gels that came in the pack to the headset and found that the volume increased 40% and I was able to achieve a comfortable fit. The headset is small enough and light enough that the gel holds the headset in the ear. I was about to give up on this headset (and all earhook type Bluetooth headsets) prior to getting the gels. If you are looking for a comfortable (and econimical) alternative for earhook type headsets, I strongly recommend that you give these a try. They are well worth the price.

Answer: Positive

Question: My husband and I are expecting our first baby any day now. We opted to get a childbirth video versus attending a class. After doing some research and getting reccomendations from friends, I decided to purchase this video. While the information on the DVD is helpful and each segment is clear and easy to understand, the instructor presented it in such a way that made extremely painful to watch.The instructor continuously makes annoying jokes, mocks pregnant women and their partners, using the most unfunny and unflattering impersonations imaginable. Watching this woman's attempt stand-up routine was so uncomfortable that we often found ourselves fast forwarding through a lot of it. Please believe that neither me or my husband laughed during this DVD. Not once.I wish we had just gone to childbirth class.

Answer: Negative

Question: Clan of the cave bear is about a Cro-Magnon girl named Ayla. She is orphaned during an earthquake as a child. When she is attacked by a lion she is found nearly dead by a clan of Neanderthals. She is nursed back to health and is adopted by the clans medicine woman.Clan of the Cave Bear ( as well as the future books in the series )is thoroughly researched). The story is based on actual archealogical findings. The character Creb is a medicine man who has severe physical deformities. An actual neanderthal skeleton was discovered that apears to have the same deformaties that Creb has. The story is fictionalized but it is amazing how they cancreate a culture based on a few artifacts. Since there is no written record, "Clan of the Cave Bear " is as close to an actual ethnography of early modern humans as you can get.
