I bought on 11.3.2018+shipping time so I didn't wait till sales started because I thought it was a great deal and I need it for work, why not. Well on 11.15 it changed itself to airplane mode without me doing it. So fast and deadly. I tried everything to get rid of it; even returned pc tower to default settings. But nothing brought back the Wi-Fi. Adapter just died or something was broken... Why or how I don't know but obviously this refurbished computer was far from being good. Funny fact is that the new Under Armour or other Sneakers can be returned during the month period. Here under 2 weeks the seller trying to negotiate and Amazon didn't care. Amazon allows these companies to rip you off if it allows them to sell their crap without proper refund policy. Electronics shouldn't be restricted to return less time than Sneakers! Don't you agree?! Now I'm fighting for refund.Don't make my mistake, buy better quality from the start!!!
