[EX Q]: Currently, there are no wholes throughout the bed. But, for some reason when I wake up. The bed is already out of air. I only weigh 120lbs. I don't understand why it does that. Please save your money, when you start to have the same problem.
[EX A]: Negative

[EX Q]: What a great album!!! I never knew she sang as well. I have seen her in French movies and enjoyed greatly her acting in those movies. Now I even adore her more, because not only can she act, but she can sing as well!!!Go Charlotte Go!!!! Can't wait for her next album.
[EX A]: Positive

[EX Q]: I take photos of antique prints for sale in a controlled condition (photo lights, etc), making correct color of utmost importance. The card is small to set the white balance on my camera, but works wonderfully with Adobe Lightroom to set the custom white balance. I am new to photography, but have found that this combination is working well for me.
[EX A]:
Positive
