I use this for my DJI Osmo pocket 3 and it work really well. Worth the price. I just slot it in the adapter and slot that in my MacBook to access the files. Great quality and really fast.

I recently picked up the SanDisk 64GB microSD card for my CCTV camera, and it’s been absolutely spot on. Fitting it into the camera was a piece of cake – it slotted right in and was instantly recognised by the system. No messing about with formatting or setup, which was a relief.Performance-wise, this card is awesome. My CCTV records in high-definition, and the footage is always smooth with zero lag or buffering. Transferring files to my computer is a breeze too. With 64GB of storage, there’s loads of room for continuous recording. My camera runs 24/7, and this card can store days of footage before it starts to overwrite older files. No worries about missing any important moments.This SanDisk card has been super reliable. It works perfectly even in extreme weather, which is great since my camera is outside. I haven’t had any issues with data corruption or errors. SanDisk’s known for durability, and this card lives up to that – it can handle tough conditions, making it perfect for a security setup that’s always on.For the price, the performance and reliability are brilliant. It’s a cost-effective way to boost your camera’s storage. Overall, I’d highly recommend the SanDisk 64GB microSD card to anyone looking to upgrade their CCTV system. It’s fast, spacious, and reliable – exactly what you need for a security camera.

I added a 512GB microSD card to my Steam Deck and it’s been a fantastic upgrade. Super simple to install—just pop it in, format it in the settings, and you’re ready to go. Took barely any time.Performance is surprisingly solid. I’ve played games like Hades, Hollow Knight, and even Elden Ring from the card, and they all run really well. Load times are slightly longer than the SSD, but nothing that bothers me at all.512GB gives me a ton of extra space without breaking the bank. I can keep a good chunk of my library installed and switch between games without worrying about deleting anything.If you’re not ready to swap the internal SSD but need more room, a 512GB microSD card is a great middle ground. Totally worth it!

Works well and does what it says, good value for money considering the size

I bought the SanDisk 1TB Extreme microSDXC Card to expand the storage on my GoPro and laptop, and it’s been nothing short of excellent. If you’re looking for massive capacity, high speed, and reliability for video recording or file storage, this is a brilliant choice.First off, the packaging is simple but effective — you get the microSD card itself and a full-size SD adapter, which is useful for cameras, laptops, or card readers that require standard SD slots.The card is rated A2, V30, U3, and Class 10, meaning it’s certified for extremely fast application performance, consistent 4K video recording, and general read/write speeds suitable for intensive use. I ran a few tests and got read speeds around 160MB/s and write speeds around 90MB/s — which matches the manufacturer’s claims and makes it ideal for high-res video capture.I’ve used it extensively in a GoPro Hero 10 for recording 4K60 footage, and there were no skipped frames, buffering issues, or corrupted files. It handled over three hours of continuous high-quality video recording without any problem, which is exactly what you want when you're out adventuring and can't afford to lose footage.The card is shockproof, waterproof, temperature proof, and X-ray proof, which gives extra peace of mind for travelling. I’ve taken it hiking in wet weather, exposed it to airport scanners, and even dropped it once (oops), and it’s still performing perfectly.The 1TB capacity is massive. You can store literally hundreds of hours of HD or 4K video, tens of thousands of photos, or countless apps and documents — all without worrying about running out of space. It’s also brilliant for expanding the storage of smartphones or tablets that support expandable memory.The SD adapter is sturdy and allows easy file transfers to laptops or desktop computers without needing a separate card reader.If I had one small caution, it’s that you need to ensure your device can actually handle 1TB microSD cards — older devices might not support cards above 512GB, so double-check first.Overall, the SanDisk 1TB Extreme card is everything you want: fast, reliable, rugged, and absolutely enormous. Highly recommended for photographers, videographers, content creators, and heavy mobile users!

Good, reliable and fast.
