The shipment was carried by colissimo with delivery against signature. What was remarkable was free shipping Germany. Crucial 4GB DDR3 PC3 module corresponds exactly to the desired product to increase the RAM from my laptop Asus N53V. So much so that I ordered a new module with the same characteristics from this time Amazon France, at a price even lower. It seems superfluous to add that all my orders placed in the most diverse fields at Amazon and its partners often, m 'have always fully satisfied. The "customer satisfaction" seems to be the hallmark of this reputable brand. Thank you.
