[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]: The sizing of this costume was fairly accurate but it very cheaply made. After only a few wears, the mask and belt both broke. I wouldn't recommend this costume.
[EX A]: Negative

[EX Q]: This one makes too small and too fine a grind of pepper to be useful in cooking. You'll be cranking away on this thing for ten minutes before you get enough crushed pepper to flavor anything.
[EX A]:
Negative
