Review: Produit reçu sans aucun défaut, il était indiqué carte légèrement abimé, même à la loupe je n'ai rien constaté. Installation sans soucis et reconnu par ma CM immédiatement. Par sécurité j'ai lancé un test approfondi de la mémoire. Tout est OK et cela fonctionne parfaitement depuis 1 mois. RAS
Review: Took about a week to ship. Pulled out the old sticks and put these puppies in and was done in less than 5 mins! My only concern would be the package it was shipped in. It was just in a bubble wrapped envelope. It would be nice if something sturdy was put around the RAM to prevent bending. Mail couriers aren't always the gentlest. Otherwise, great product!

### ⭐⭐⭐⭐⭐ Review
*by B***B on 4 September 2016*

Works great and arrived quickly. Not too much more to say. I had a friend who was moving and getting rid of a bunch of things. One was an older Dell 64 bit computer that they were giving away. This was pretty slow since it had the bare minimum of memory installed so Windoze really crawled. So I ordered 8 GB of this memory and now that old slow machine is still usable as an additional windoze box. I use Windoze as little as possible since spend most of my time running Linux, but every now and then I need something that only runs on Windoze. If I needed more of this memory in the future I would buy again.
