Pros: No problem getting it to install and register. Had heard horror stories of cheaper places selling copies with unusable product keys. Newegg sells quality items.

Cons: No cons with the product per se. I had some trouble finding out how my machine would boot from a USB drive, but that was a machine issue, not a product problem. Once I figured that out, everything went extremely smoothly.

Overall Review: I've always been pleased with the products I purchased from Newegg. Items always as advertised and shipped promptly. Will definitely use them again, and highly recommend.
