Amazon BasicsMicro SDXC Memory Card with Full Size Adapter, A2, U3, Read Speed up to 100 MB/s, 128 GB, Black

The Amazon Basics Micro SDXC 128 GB works perfectly. The read speed is excellent and exactly as advertised, making it great for recording high-resolution videos and transferring large files quickly. The included full-size adapter is very convenient, allowing me to use it in both my camera and laptop without any issues.For the price, the performance and reliability are outstanding. A solid choice if you’re looking for a versatile and affordable memory card. Highly recommended!

Works as advertised, with high speed and quality when in use with my Windows computer. It is compatible with all formats, and maintains the picture/video quality uploaded. However, a slight amount of the 256 storage is used by the chip.

Installed this in my Tapo security cam, and it’s been running like a champ. Continuous recording, playback, and motion clips all work smoothly, and I don’t have to babysit it. It handles the loop recording without stuttering, which is all I really care about for home security.For the price, it’s unbeatable. No need to overspend on a “fancy” branded card when this does exactly what you need. If you’re running Tapo or similar cams, this is an easy, affordable choice that just works.

This worked perfectly for my son’s tablet! He’s always downloading games and apps, so he used to run out of space constantly and we’d have to delete things. Now with this 128GB card, he has plenty of storage for everything he wants. It was super easy to install and worked right away. The price was great, shipping was fast, and I’ll definitely be buying another one when we need more storage for our other devices.

These micro cards appear to be as good as the name brand cards. The pricing was great, that is before Amazon raised the price from $11.05 to $17.99. That much of a price increase is ridiculous. Won't be buying anymore of this brand at that price.

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.

This Amazon Basic 256GB micro SD card functions pretty good iny DJI Drone. I was able to record all 4 batteries in the highest setting and then transferred all to my new laptop/tablet quickly. I was using several 64gb cards but it got old having to swap out cards all the time. Especially when my fingers are dirty. Ive only had the card a couple days so can't really advise on the longevity or lifespa, but hope it lasts me for a lifetime of continuous use. It was very easy to use. Just open the box it was shipped in, find the SD card slot on your device, and slide it in till it clicks. Definitely recommend to others for its coo-coo crazy low price.One more thing, always format the card in device when first using to get synced. Adios amigos!

Got this to put in my Wyze cam 4 and it holds about 15 days worth of recording if you record 24 hours a day, so it's a very good amount of time before it starts to rewrite. It just pops right in, very easy to use, works great, there is no formatting issues, it works perfectly with the Wyze cam. It looks like an other micro SD card. Very happy with my purchase.
