[EX Q]: Well this stuff was crumbly and would not stick to itself. It was like wat sand. I couldn’t knead it or work with it at all. Added water and pushed it in the mold and it cracked in thousands of pieces. Worthless stuff don’t buy it.
[EX A]: negative

[EX Q]: 4 times now I tried to order this DVD--twice from elsewhere, twice now via Amazon, and ALL times I was sent Blu-ray even though I ordered DVD! The DVD is listed separately from blu-ray: the boxes are different, so I zoomed the photo claiming the "DVD" format, ordered clearly under the "DVD", and under the lower DVD pricing, as Blu-rays are sold at a higher price. Each time I am sent the Blu-ray!!!! I am so frustrated at this terrible advertising! Why is the photo/descrption/price for DVD offered online if only Blu-ray is available? Blu-ray doe NOT work on my DVD player and just want what is clearly marked as offered!
[EX A]: negative

[EX Q]: Work very well. Very happy. Just make sure you don't go too far on the last step creates a little too much tension and caused headaches. But once I heated it up and reformed it was just fine. Very happy.
[EX A]:
positive
