    Got it quick, came in a cushioned envelope with a media bag (grey plastic bag with magnetic shielding) inside. Got it quick and it's working as advertised. It's exactly as described and pictured and it's working well.

    Item as described, brand new! Fast shipping. Good packaging. This is the second time I buy from this seller. In these times when we find ourselves receiving purchases damaged, nonfunctional. or not what they were described, this one stands out as a solid one. Very Highly Recommended!

    Excellent seller. Had an issue with one of two sets that arrived and the seller quickly sent a prepaid return label as well as a new set to me. Overall unfortunate that a wrong/bad set was sent but the seller handled it perfectly. Both sets which I now have work and run at the speed and size advertised. Will likely buy again in the future.

    Excellent products that helped me get exactly what I was looking for on my computer. Was not unfortunately not able to install both on my one laptop because I think of power constraints, but I have my secondary one installed on another laptop so now I have two laptops with 16GB of RAM instead of 8GB. And that’s really all I was hoping to achieve in the end.
