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.

Couldn't be any better! High Value Item!!!
The media could not be loaded. This Amazon Basics 256GB Micro SDXC card has been an absolute lifesaver for all my devices! I picked this up for my Nintendo Switch, and it has exceeded all my expectations.First off, the 256 GB capacity is fantastic. It's more than enough space for a ton of games, photos, and videos without having to constantly worry about running out of storage. I've loaded it up with digital games, and I still have plenty of room to spare.The A2 and U3 ratings are no joke. The read speed of up to 100 MB/s is noticeably fast. Games on my Switch load quickly, and transferring large files from my drone or camera to my computer is a breeze. I've also used it in my Android phone, and app performance and photo saving are incredibly snappy.The included full-size SD adapter is a huge bonus, making it super versatile. I can easily pop it into my laptop's SD card slot or transfer files to other devices without needing a separate adapter.For an Amazon Basics product, the reliability and performance are truly top-notch, especially for the price. It's a no-brainer if you're looking for a high-capacity, fast, and dependable micro SD card without breaking the bank. Highly, highly recommend

“Reliable storage with solid speed and video support”
This card delivers good read/write speeds for the price—great for Full HD and 4K video recording. The 256GB capacity is accurate and works well with phones, tablets, cameras, and even Nintendo Switch. It comes pre-formatted as exFAT, so it’s ready for large files. I tested it and the storage is genuine, not a knockoff. Took off one star because it’s not quite as fast as premium brands, but for everyday use, it’s a great value.

Works in microSD devices
Works as expected, sort of. I put this into a trail camera that requires this size card and it works fine. I put the other one into an SDCARD adapter for my other trail camera and it does not work there (I thought it would work in both with the adapter, but it doesn't).
