Great memory card for the money. Works well and reliable.

I brought 3 of these to use in some cheap security cameras I had recently purchased. They formatted well and work perfectly. I have used this brand many times over the years and they have always given good service. Comes well packaged and with a converter to turn them into a standard (larger) SD card. A decent card at a decent price! what more can I say?

Got this SanDisk 256GB Extreme microSDXC for my Osmo Pocket 3 because, let’s be real, that little camera needs a card that can keep up—and this one absolutely delivers.First off, it works straight out of the box. No faffing around, no formatting nightmares. Slotted it in, and boom—ready to shoot. I’ve been filming in 4K with zero lag or buffering. It handles high-bitrate footage like a pro, and I haven’t had a single dropout or corrupted file. Smooth as butter.Transfer speeds? Lightning. Plugged it into my laptop and the videos zipped across in no time. No watching a slow-moving progress bar while contemplating the meaning of life. 😂Also, 256GB is a sweet spot if you’re doing a lot of filming. I went out for a full weekend of shooting and didn’t even come close to filling it.If you’ve got an Osmo Pocket 3 (or anything that demands a high-speed card), this SanDisk is a no-brainer. Fast, reliable, and tough—just how I like my tech.

Exactly as described. No problems. Very easy to install into my device. Highly recommended. The only thing I would mention is do your research into the different options as you may be paying more for no real world difference. Overall good value.
