Excellent laptop. Was delivered as promised.Although it is not Intel Core i7-4900MQ, but i7-4810 processor, it is fast enough to run applications like SolidWSorks and other high end engineering software.New laptops with similar configuration cost in the range of $2500 - $3500, but not many will allow to install 2 hard drives. I added 16 GB of RAM (making it total 32 GB), added 500 GB mSATA drive. The entire process took about half an hour. The only problem I had is the fact that originally laptop came with SATA configured in BIOS as RAID, not AHCP.I had to do full reinstallation of Windows 10 Pro because of it. That is when I ran into the second obstacle.In description it mentioned that laptop would come with a document that would have Key for Windows 10 just for this exact purpose (to reinstall Windows 10 software). My laptop came without any documentation except sales receipt and no Windows 10 Keyon the receipt. The utility that can show Windows 10 Key read the number, but it didn't work during Windows 10 installation. I had to use the Windows 7 Key from the sticker under battery.The screen, although not the top of the line that Dell had, but is good for the size of the Laptop (15.6").In summation, I think that this is excellent laptop, especially if you are on the budget. If I had to buy laptop now, I would buy the same laptop again and I would recommend this laptop to everyone.I just hope that Dell would continue to make laptop like this in the future, even if it cost more.
