Input: Consider Input: 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.

Output: Negative


Input: Consider Input: Very intuitive in explaining the basic concepts and the fundamental and widely used methods in continuous-time finance. No deep background in math is required to have a good grasp of this book. I believe it is intuition rather than fancy skills that is important to build up interest and passion for studying a hard topic such as continuous-time finance.

Output: Positive


Input: Consider Input: I bought this because I was tired of wearing myself out in other ways (haha). I am pretty much a nontoy user, but when I saw what all this thing could do and for the price, I was hooked! It came on time in very discreet packaging (Thank you Lord!). A regular Amazon Box and a black bag on the inside, completely sealed. I don't live alone and was worried someone else would open it.I wasn't expecting it to be so HUGE. I took it slow, and was able to use it after a little coaxing. A little painful, but eventually I found my rhythym and it was AMAZING. Controls are easy to reach and the spinning feature is heavenly!So, it takes getting used to if you are inexperienced, but it's definitely worth it!


Output: Positive
