Bests & Worsts Reviews from Amazon

You should be very careful when buying SD cards online. One way I knew this listing was legitimate was by checking the merchant during order review, mine showed as "Amazon.com Services LLC". Upon arrival I checked the packaging which had no misprints, and the micro SD card graphics were crisp and had white sides, the model number on the packaging also matched the model written on the card's backside, all pointing to a legitimate item. Last test was speed and storage test, everything checked out in terms of storage but my speeds were a little slower but I am attributing this to my very old laptop.
