impressed with their consistent performance
Why did you pick this product vs others?:After using the Amazon Basics 64GB MicroSDXC cards for my GoPro Hero 9 over the past three months, I've been thoroughly impressed with their consistent performance. The two-pack arrived in simple but secure packaging, and each card came with a full-size adapter that's proven handy when transferring files to my laptop. What first caught my attention was the A2 and U3 ratings, which promised fast app performance and 4K video capability - specs that initially made me skeptical given the affordable price.Recording 4K footage at 60fps has become my standard practice with these cards, and they've handled it without a single dropped frame or overheating warning. I regularly shoot hour-long sessions while snorkeling, and the cards maintain steady write speeds even when the camera gets warm in direct sunlight. The claimed 100MB/s read speed feels accurate when I'm transferring files to my computer - a 30GB dive session transfers in about 5 minutes, which is significantly faster than the generic cards I used previously.Memory quality:What surprised me most was how well these cards perform with the GoPro's advanced features. Timewarp videos, 240fps slow motion, and HERO mode photos all save instantly without any lag or buffering. I've filled these cards completely multiple times during road trips, and they've never corrupted files or failed to save important moments, which happened occasionally with my old cards. The included adapters work perfectly in my DSLR too, making them versatile for all my photography needs.Durability has been excellent despite heavy use in various environments. After being submerged in saltwater, exposed to desert heat, and frozen during winter hikes (accidentally left in my jacket pocket), both cards still function flawlessly. The black finish shows no signs of wear, and the locking mechanism on the adapters remains firm after dozens of swaps between devices. I appreciate that they maintain consistent performance even when nearly full - some cards slow down significantly when storage space gets low.Reliability:For the price of this two-pack, the value is outstanding. I've tested these side-by-side with name brand cards that cost twice as much, and the Amazon Basics cards match them in real-world performance. Having two identical cards means I always have a backup ready when one is transferring files, and the peace of mind knowing both are reliable is worth the purchase alone. They've become my default recommendation for fellow action camera enthusiasts.After recording over 500GB of footage across multiple adventures, I can confidently say these microSD cards outperform their price point. The combination of speed, reliability, and included adapters makes them ideal for anyone needing dependable storage for 4K video. They've handled everything from professional shoots to family vacations without fail, proving you don't need to spend a fortune for quality memory cards that keep up with demanding cameras.

Well, it's not a counterfeit... which would have been awkward.
I think we've all been there, hovering over the "Buy Now" button for a surprisingly cheap memory card, fully expecting a tiny 4GB card with a "256GB" sticker cleverly placed on it. The price on this Amazon Basics card had me raising an eyebrow, so naturally, my paranoia kicked in the moment it arrived.Before this card went anywhere near my Nintendo Switch, I plugged it into my computer to run a check. I was ready to screen-capture the fake capacity and write a scathing, "I knew it!" review. But, to my surprise, and frankly, my slight disappointment (I was ready for a good rant), the full 256GB reported back. It's the real deal.There's a certain irony in being suspicious of a product sold by Amazon, with their name plastered right on it. The thought of them scamming their own customers with a fake card was pretty hilarious, and I'm glad it was just a thought. It's been working perfectly in my Switch for a few weeks now, downloads are reasonably fast, and I haven't had a single issue.In Short: If you're looking for a memory card and are tired of playing storage roulette with mysterious third-party sellers, this is a solid choice. It does exactly what it's supposed to do, and you can be pretty sure you're actually getting the storage you paid for.Pros:It's a legitimate card with the advertised storage space.The price is very reasonable.The read speeds are decent for the price point and work well for gaming.Cons:Honestly, none so far.

fast-loading powerful TF card
I bought these as my new 3D printer requires some TF cards. This is super fast loading for it. My 3D printer instantly recognized the file. It also is pretty reliable as it works great on it. I can save more than 100~ STL files so that I believe this has a good storage capacity as well!

Does its job, costs less—what’s not to like?
Used this Amazon Basics Micro SDXC card for about two weeks now. It works just like the name brands but without the “why did I pay that much?” regret.No glitches, no weird behavior—just a good memory card doing what it's supposed to do, quietly and affordably.Would I recommend it? Absolutely. It’s basic in the best way.
