My school had a partnership (I think) with them. They supplied over 200 laptops. Windows 7, Core i7 and 4GB RAM. They were TERRIBLY SLOW, prone to BSODs and froze all the time. When they were not on their period, however, they were fairly ok. Fairly. Their displays were very good, though.
I’ve not been chanced to buy a Zinox (yet?), but I doubt they’d be any worse than all the other laptops… afterall, the CPU, memory chips, and motherboard are pretty much the same* commodity parts you’ll find in an Acer, Xiaomi or Voyo
*I could be wrong - in the sense that they use the services of a lower tier OEM - but the discussion sounded as if they (Zinox) actually manufactured anything.
Zinox definitely doesn’t have the same level of resources allocated to quality assurance as you might find with your usual HP, Dell, or Toshiba.
Anybody can go to China to get whitelabelled laptops made. The reason you’d trust a Dell over Zinox is the same as why you’d rather get an Asus motherboard over a nameless one if you’re into building your own PC. Or say Corsair RAM modules over the ones you get on Alibaba.
Long story short, I can build you two desktops while keeping the obvious specs similar, but the performance of both miles apart. What Zinox is doing is counting on the fact that the average Nigerian will not look beyond those “obvious” specs. So its a Core i7, but is it Sandy Bridge from 2011, or something more recent. You know, stuff like that.
I used Zinox when i was young, paid a large sum for a shitty spec computer, that’s when I realized you can build your own system yourself. save yourself the stress and avoid zinox. I’d rather have Cancer than buy from Zinox.
