SanDisk Extreme 128 GB microSDXC Memory Card + SD Adapter with A2 App Performance + Rescue Pro Deluxe, Up to 160 MB/s, Class 10, UHS-I, U3, V30 , Red/Gold

The media could not be loaded. I bought two of these to use in wifi cameras at a construction site, and they’ve been running 24/7 for over three months now with no issues. The footage is 2K and the cards handle the looping video perfectly with no glitches, break-ups, or corrupted files so far.Setup was very simple. The cameras auto-formatted the cards and were ready to go right away. I haven’t had to use the SD adapter or the included software, but it’s nice to have them included just in case.The cards have also stood up well to challenging site conditions. There was damp, later dust, and direct sunlight. No signs of failure or degradation yet.I use these cards on the cameras' local storage option (not the cloud storage), which saves money. I’m very happy with the performance and reliability so far.I have attached a video to illustrate the video quality downloaded from the device - there were no glitches or quality issues.

This card is built for high-speed mobile storage and 4K video capture. The A2 rating means it’s optimised for app loading and multitasking on Android devices—ideal for tablets, phones, and even handheld consoles. In benchmark tests, it hit 169 MB/s read and 103 MB/s write speeds using SanDisk’s MobileMate USB 3.0 reader1. Other readers showed lower speeds (around 99 MB/s read, 87 MB/s write), so pairing it with a good reader matters.The V30 rating guarantees 30 MB/s sustained write speed, making it reliable for 4K UHD recording on action cams, drones, and mirrorless cameras. The included SD adapter makes it easy to slot into laptops or DSLRs.✅ ProsFast read/write speeds—great for 4K video and app-heavy devicesA2 app performance—smooth multitasking and fast app launchesWide compatibility—Android, GoPro, Nintendo Switch, DSLRIncludes SD adapter—easy transfer to PC or cameraRescuePRO software—recover deleted files if neededDurable build—shockproof, waterproof, X-ray proof⚠️ ConsMax speed only with SanDisk reader—other readers may bottleneck performance1No hard case included—just retail packagingPrice fluctuates—watch for dealsNot UHS-II—still solid, but not top-tier for pro camerasRecovery software is time-limited—requires activation🧍‍♂️ Personal VerdictUsed this in a GoPro and Android phone—loaded apps fast, handled 4K footage without stutter, and transferred files quickly to PC. For under £25, it’s a proper upgrade if you want speed, reliability, and flexibility across devices.

Great. Bought for my dashcam after previous disappointment with different brand. This one is compatible, easy to format, just read Google suggestions and you can do all yourself. Came with little reading device, if your laptop is suitable for, then it's great advantage. Fit perfectly in camera, seems sturdy enough to not break or scratch easily.After formatting I drove around in the night and then I checked all videos are clear to see and recorded. Happy with video recording, now I don't have to be worried as I was before just in case of accident. Thank you

Works good. Disappointed in the brand. Just seen the black friday sales. I bought this at normal price for £108. According to black friday sales this is 67% off and £97!!! Wtf Sandisk! hike the price by 300% to around £280 just before black friday to create a pretend sale!DO NOT FALL FOR THE MARKETING PEOPLE.Its a good card but the price is not as good as it seems

Good and useful. Easy to use, classic. The quality is okay

Great, it works as intended and my laptop had an sd slot. has a lot of storage too!

The number of devices that MicroSD cards work with now has increased demand, which in turn has really brought the price down of these fantastic cards. I don't use any other brand now that I know I can rely on SanDisk (having previously used them for several years without a fail in a dashcam and tablets).On top of being ultra reliable, they come with A2 App performance. You may think A2 isn't as good as A1, but it actually means read and write speeds are at least doubled (usually more). This makes them ideal for recording video in a dashcam, CCTV camera or video doorbell that produces high definition video at a high frame rate (does footage look laggy if movement is fast?)It comes with a microSD to SD adapter so that the card can be plugged directly into a card reader or laptop. It also comes with recovery software but I have never had to use it in the past and don't expect to in the future either.I will continue to trust in and spend my money on SanDisk and recommend that you do the same. You will not be disappointed.If you found my review helpful, please remember to let me know.
