    • Just an amazing sd card
Style: Memory Card Only Capacity: 32GB
This is just an amazing item. It is high quality and how you would expect a Sandisk memory card to be. It functions perfectly and is indeed 32 gigabytes. I would say this is an amazing bang for your buck.

    • Reliable Performance
Style: Memory Card Only Capacity: 128GB
This memory card is a solid choice for any compact or mid-range point-and-shoot camera. It's fast enough to keep up with most recording needs and the storage capacity is great (although I haven't quite filled it yet). I mainly use this card in my trail camera, where it records clear footage of wildlife like coyotes, deer, and even the occasional bobcat. The image quality is good enough for me; sometimes you can see individual hairs on a coyote's tail! This card is perfect if you want to capture those unexpected moments without worrying about running out of space too soon. I was originally looking at some cheaper brands but decided to go with SanDisk because they have a solid reputation and I wanted something reliable (I mean, you don't want your trail camera to fail when there's a mountain lion lurking around). Now, the write speed is advertised as up to 140MB/s, which is pretty good for its class. But who knows what that really means in the real world? I haven't noticed any issues with lag or dropped frames though (though sometimes it takes forever for my computer to read the card, but maybe that's just a problem with my old laptop). Overall, this is an excellent choice for anyone looking for a reliable and fast SDXC card. It's worth every penny if you ask me. ... show more

Arrived quickly and works perfectly. Was surprised that all of my current devices have ports for this memory card, so using it to get pictures from my Canon camera is super easy. Thank you!
