Seller advertised this computer as coming with Windows 10 Pro, one of the main reasons I purchased. The product instead has only Windows 10 Home. An honest seller would provide a free update.

Ex Output:
negative


Ex Input:
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 Output:
negative


Ex Input:
This book was a page turner from the very start. I found it very interesting, being a native of San Diego, to hear and visualize the places the author talked.

Ex Output:

positive
