[Q]: I bought this air mattress to use while my new bed was being shipped from back east, the bed lost air every night and I woke up almost on the floor. I tried to send it back but it was impossible to get back into the box.
[A]: Negative

[Q]: I was impressed with speed of delivery, condition of product & quality of packaging for the product.The soundtrack itself is wonderful as I saw the original movie when it came out and feel Madonna & Antonio deserved a better review than they got for their performances.
[A]: Positive

[Q]: I bought this in hopes to reduce some small bumps on my cheeks and even out my skin tone. What I got was horrible acne and sores all over my face. The very next morning after using it I woke up with zits on my face! I haven't had acne since I was a teenager. My first thought was, it must be cleaning out the pores, thus the breakout, but after three weeks of using it every other day, my face is covered in sores that won't heal! I don't want to say it's a bad product, because it obviously works for most of the people that have written reviews, but my experience has not been good. I will never use it again. I'm just glad I got it on sale for $45. C'est la vie.
