[EX Q]: This LED lights did not stick to my walls. I set them up in my room (efficiently, I made sure they shouldnt fall off) and left for a couple hours. When I came back they had completely fallen off. I messaged them to see if I could get my money back or if another one could be sent to me because I thought maybe the one I received was defective and they never even responded and its been 2 weeks.
[EX A]: negative

[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]: GARBAGE!!! One pair arrived with a nice tear already in the material. They pill IMMEDIATELY just while wearing them and it gets worse upon washing regardless of a gentle cycle and avoiding the dryer. ABSOLUTELY WORTHLESS!
[EX A]:
negative
