Seller replaced stock SSD with an extremely cheap and very slow Chinese brand "Kingfast". This degraded the performance so bad I couldn't even play 1080p videos without problems. Would take several minutes to sort items in folders, just awful performance. No stock WIFI, the cheap wifi dongle it shipped with can be purchased for $5 and doesn't stay connected. Memory was a junk brand as well. I had to replace the SSD, memory and install the wifi module, all of which cost me about $250, making the total cost of this unit nearly $600, not to mention my time dealing with problems. Seller completely misrepresented this unit and should be delisted. I guess we all have to make money some way, too bad some sellers do it this way, completely counter productive.
