Delivery 16 days, parcel tracked. Packed well (cardboard box and many layers of expanded polyethylene), all whole, legs smooth. The processor took for samsung p538 (the maximum processor for my model), everything came without problems. The processor can be seen that not new (there are traces of thermal paste), but there are no scratches and abrasions. The only thing is that the temperature is quite high, about 82 degrees celsius, but this is due to the weak cooling system of my laptop.
