Dealer:
Relatively fast delivery to Greece (rare). Ware was super packed and protected.
Goods:
Have installed the memory immediately after Erhallt (iMac 27 Spring 2011) and Niels slipped at the second attempt flawlessly (You really have very firmly closed).
If no answer after installing the iMac, then just continue to expand the memory and reinstall with some force (not too tight).
With me in the rest of the house (which the company always is) was from memory Elpida installed which comes from Taiwan, so nothing original.
Conclusion:
Highly Recommended both sellers and goods. Keep it up
