I purchased 2 times, 4 laptops each, every time one laptop comes with problems. I live in another country so is impossible for me to return laptops, as seller requested, so I sent to a local tech service and ask seller to send me the spare parts with problem (in this case, the screen is faulty and needs replacement)... no answer. So thats why I put the low rating, the other laptops are fine, but 1 of 4 every time comes wrong... will look for another supplier.
