[EX Q]: Over the winter, i seem to gain alot of weight. As a high school quarterback, that is not acceptable. Last summer, i think i went from 160 to 150. That's my gross weight loss. I'm not even talking about how much fat i lost. I gained a good amount of muscle over the summer, so i probably lost over 15 lbs of fat. I got my six pack back, and life was great. After the season, i just quit, and now my six pack is back in the fridge. I'll probably order some up next week and start again. These are great, and the results are amazing.
[EX A]: Positive

[EX Q]: 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!
[EX A]: Negative

[EX Q]: According to the specifications this headset supports Bluetooth 1.2, as well as the Advanced Audio Distribution Profile (A2DP) and the Audio Video Remote Control Profile (AVRCP). I could not get any sound to come out when connected with my Sony Ericsson w600i in phone or Walkman mode, and people could not hear me when I called them. I tried every setting possible, read the instructional booklets for each device and the thing still wouldn't to anything when connected. I am guessing that this headset works fantastically with any Motorola device, but as far as I'm concerned this product is guilty of false advertising. After this experience I do not plan on buying any Motorola Bluetooth devices.
