[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]: This thing does not tell you which app to download. I turned it on in range of WiFi and it would not connect regardless of which of the 3 apps I used. Thought that buying a cheap product was the way to go... you get what you pay for. In an age of cheap technology, it is astonishing that it comes with so little information. I am a reasonably tech savvy individual, and the fact that I can’t figure it out speaks to the low quality of the product. DO NOT BUY!
[EX A]: negative

[EX Q]: I feel the good quality using it to our car and furnitures. Polished really good no sign of scratches. I wash ut after cleaning and let it dry and use it again. Generally , it works very well.
[EX A]:
positive
