[EX Q]: All the features are nice, TV Guide worked (note that browsing and setting recording preferences is very SLOW), BUT when the TV Guide is downloading (all the time) or you are recording / playing from the hard drive you constantly hear a grinding sound from the hard drive. These guys must have used a cheap hard drive or something. I have the Amazon return slip on my desk......
[EX A]: Negative

[EX Q]: I think this is a case of my expectations being too high. I was so encouraged by the great reviews of this product, I really was expecting a miracle. After only wearing this twice, it is stretched out. At first, I thought perhaps it would regain it's shape after a few hours but nope! It's no better than a cheap, fashion corset. It will smooth things out so there's less bulging under the clothes but I was looking for a real "waist trainer", something that would go on tight and STAY tight. Considering I found this product when I searched specifically for "waist trainer", I would say the claims of this product are misleading. It is shapewear, it is NOT a "cincher" or a "trainer".
[EX A]: Negative

[EX Q]: WARNING!!! CAUTION!!! Parents do not waste your hard earned money or valuable time with this toy. I am the proud father of two boys who were so excited to receive this batcave from Santa. Boy were they disappointed with the substandard quality. This has to be the worst display of a children's toy that I have seen in awhile. I feel that Mattel has stolen from me by misrepresenting this gypsy junk as an actual toy. Please do not purchase!
