[EX Q]: Received an older model than pictured, screen has 2 flaws, crashed after installing microsoft office. I needed the computer for my office, and little to nothing was done to refurbish the unit I was sent. I had to reinstall the operating system myself after half a day I got the thing working to my satisfaction. I would not recommend buying anything from these folks again.
[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]: Hair has minimal shedding, very soft for a synthetic hair no tangle so far, looks like human hair, this was a great buy, definitely buying from this company again 👍
[EX A]:
positive
