The delivery took place quickly and smoothly. The installation in our old HP PC was as unproblematic. Unfortunately, it turned out that although the memory are printed with the name of Samsung, they're from Silicon Mountain (Sandra software used for reading).

The price of 30 is far too high for the supposed Samsung memory.
