Genuine SanDisk. I import the cards directly from overseas, which allows me sell them at a much lower price.

In stock, ready for pick up or prompt delivery (next day if you buy before 4pm). Pickup is in Auckland city centre on week days 8am-4pm, or in Bucklands beach at any time.

• Sandisk part number: SDSDQXN-064G (newer version of SDSDQXL-064G)

Sandisk Extreme is worth extra dollars that you pay for it. You will not find better 64GB microSDXC card for this price. Not all Class 10 microSD cards have the same data write speeds. If you plan to shoot HD video, this card is a must.

• Officially recommended by GoPro for HERO3/3+/4 for shooting in 4K, 2.7K and Protune video modes, see GoPro web site: http://tinyurl.com/lz6okpq
• Perfect for action cameras
• Works great for full HD video capture with most cameras that support 64GB cards
• Ideal for Android and other smartphones and tablets that support 64GB cards. Expand the onboard memory and enjoy faster app loading and smoother full HD video capture.
• Durable design: water-proof, temperature proof, X-ray proof, shock proof. From -13ºF to 185ºF (-25ºC to 85ºC). Take your phone, tablet, or camera to the mountains, the ocean, or the desert. Even if your device doesn't survive, your SanDisk memory card will.
• Sandisk lifetime warranty. Return/refund/replacement if the card is faulty or damaged. If the card fails within a year from date of purchase, you send it back to me, and after a quick check I send you a replacement. If it fails later, I'll still be able to replace it, but it might take a bit longer, as I might have to send the card to my overseas distributor.
