[EX Q]: 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 A]: negative

[EX Q]: I love them! Much better than the toxic plastic crap from the pharmacy that was always itching me! The washing part is a little bit annoying but you will get used to it.
[EX A]: positive

[EX Q]: What I liked the most about using these Gelatin Vitamins was how quickly my nails started to grow and the strength of them. I always have had thin and brittle nails but now they are finally starting to harden. I also started noticing how much my skin has cleared up on face!
[EX A]:
positive
