These cards are the worst ones that exist. I have been buying SanDisk for 13 years and in the last 5 years, it's these ones that you see, they all break in the same spot. I put instant glue on them so that the card reader can read them, and then they become useless!! The other day, a piece got stuck in the slot and it caused 150€ worth of damage to my camera. Every time, I tremble at the thought of whether the card will be destroyed. At some point, I went to the SanDisk offices and they told me that there is no warranty because it's my own fault! My own fault, 1.2.3... but they all break in the same spot. For me, as a professional, reliability matters!! These ones here don't have it, so I will look into another company. I have over 50 cards and I don't have a problem with speed, but the durability is no longer manageable

I wouldn't change it for any other. I have married it. All my cards, and I have about 40 of them, are the same. For sound, photo, video, everything.

User of Sandisk cards here for 3 years on a Fuji mirrorless camera and I have not a single complaint to mention. Exceptional durability in all conditions, even in sub-zero temperatures. I consider it very important to not have to worry about whether a vital part of your camera, like this one, will let you down.

Although it does not reach the maximum speeds in Pentax K3 DSLR, it is really fast in raw recording along with Jpeg. A MUST for fast photography and simple video.

Possibly the most reliable memory cards on the market. The speeds are indeed high as promised by Sandisk and their durability in "extreme" conditions is confirmed (both at temperatures of around 40 degrees Celsius and close to 0!). I have been using them without reservation for the last 5, approximately, years on a DSLR camera. Flawless burst mode (5 frames per second). Recommended.

Classic piece, I have many of these. No problem ever so far in professional use for photography as well as 4K video.

I bought this specific card based on the good reviews and indeed, as long as it worked, it was fast. After the sixth month, it "crashed", neither my camera nor any computer can read it. Maybe I got a faulty one. However, I lost all the stored photos and I hadn't had the chance to back them up. I will not choose this specific company again, I will probably turn to more reliable and trustworthy (South Korean) solutions.

After some failed choices and loss of photos, it was time to test the reliability of Sandisk. So far, it works perfectly with Nikon and the readers I have with high speeds. Even though I don't use it professionally, it's tragic to lose files. I am waiting to confirm its reliability over time.

Flawless operation, it has never experienced any freezing, perfectly meets the requirements of a 4K 25p / 1080 50p video camera. I have been using Sandisk for many years and also in my camera without the slightest problem.

I have 2 of these inside my Nikon D610, and they have been working perfectly for 1 year.
The speeds they advertise are real, both in reading and writing.
