  24. B***o

    The processor venia grated around Silicon. As they may have the indecency to send something like that. I don’t understand, the little lack of care in elements that are so delicate. Apparently the person who cleaned the processor didn’t know what he was doing. And in the end I end up grating the pcb. Bad luck mine for buying in this store, and just touching my this processor. But anyway, I will never buy in this shop again. This was the purchase with which a faithful and honest customer was to be won. But unfortunately they lost it forever. Thanks for nothing.

  25. И***в

  26. E***a

    Product working perfeitamento was satisfeiro with the product and delivery time 15 days.

  27. A***o

    This is the first and very big disappointment on this site, the processor came completely not working. Money to the wind, the store did not check at all before shipping. Was all in the thermal paste, and under it cracks on the crystals. He overheated repeatedly, in short, spent money and threw it in the trash. It seems and reviews a lot of positive, but I did and bought it, now I will have to order a new one, but I’ll do it at home. I do not recommend to anyone this seller, he is either very negligent, or generally a fraud. God will judge, and I hope my money has benefited someone.

  28. J***o

    The processor arrived in good condition and well packed, shows considerable improvement in my Laptop performance as it has replaced a core i3, the product arrived in 25 days in Peru, I recommend the Core i7 640m for an upgrade in the g1 socket, temperatures are stable,✨

  29. L***l
