Genuine SanDisk. I import Sandisk memory cards and flash drives directly from overseas, which allows me sell them at much lower prices.

• 64GB size
• Sandisk item #: SDSDU-064G
• Class 10, UHS-1, read speeds up to 30MB/s (USB 3.0 reader may be necessary to achieve it); write speed lower.
• Compatible with all SDXC devices: check if your device supports 64GB cards before you buy, or ask here.
• Writeable label for easy identification and organization
• Durable design: water-proof, temperature proof, X-ray proof, shock proof. From -25C to 85C.
• Sandisk 10 year limited warranty. Local NZ 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.

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