They are Sandisk, so, you know theyre going to work. Ive had no issues using them and would definitely recommend them for your basic needs. If youre using expensive equipment, Id recommend using a card that meets its requirements otherwise, these cards a a good value and I wouldnt hesitate to purchase them again.

The card offers impressive read and write speeds. This has made transferring files from my camera to my computer a breeze, and has also allowed me to record high-quality videos and photos without any lag or delay. A top-performing and durable memory card that is well-suited for those who need to store a large amount of data and require fast transfer speeds.

Micro SD Cards are used everywhere and instead of installing device specific software to access their data you can eject the card, pop it in the reader and use any USB port to read them in your computer. The reader with a formatted card can even be used to create bootable recovery drives and complete operating systems too. They are fast and reliable.

Good price for this name brand micro SD card. I put them in a WYZE v2 indoor camera and my 2 new WYZE v3 outdoor cameras. Don't know how long they will last but I hope it is a long time.
I bought this micro sd card on the strength of its 90mb/s speed for my DJI Mavic pro drone, as it was above the minimum speed requirement needed for use in the drone. Unfortunately, it wasn't up to the job. Resulting in multiple SD card errors and an in ability for the drone to write to this card. Even at 2.7k rather than 4k. I have no idea why this is.... I formatted the card before use but the drone just wasn't having any of it. I tried the card in my Panasonic FZ1000 Camera and it worked, although it was sluggish in burst mode as well as taking multiple shots quickly in single shot mode and needed a lot of buffer time. I didn't try it in video mode, especially in 4k on my Panasonic camera...... So I can't comment on it's performance there. I have resorted to ... MoreI bought this micro sd card on the strength of its 90mb/s speed for my DJI Mavic pro drone, as it was above the minimum speed requirement needed for use in the drone.

I have resorted to using it as back up memory for my samsung phone, which it seems to cope with ok. If you are after a fast card..... I wouldn't bother. Perhaps I had a bad card? I don't know. I can only comment on my experience with the card I have..... I wasn't impressed.
I only use Sandisk Extreme or Extreme Pro cards for my GoPro and digital camera. Never purchase them from Amazon. Only a reputable source like the Western Digital Store. I have cards that are 10 years old and still working good as new. They have never let me down.
I picked one up on sale back when they were pretty expensive. They are ridiculously cheap now. It replaced external HDD, USB jump drives and other methods for transporting data. Never regretted it, had many uses and benefits. Still lots faster than my cloud transfers due to crappy AT&T service. Mostly copied data from wired connection at work to the card and used data at home. Faster use than many other methods.
I bought two of these. I actually use these for computer file storage because they are so compact and are very covert for portable applications. If you think about it, 5 of these stacked up is the equivalent of 5TB but in under the size of a few coins. It is amazing how far technology has come. The quality is outstanding as usual -no corrupted files, transfers quickly, gets heated when writing very large quantities for a bit of time, but I rarely do that so not an issue. They do seem to keep cool enough to maintain the higher speed so that is good. Remember, to get the best speeds, you need the right readers, usb cables, and ports. This all works together. I have used the 256gb, 512gb, and now 1tb sizes of these and so to extrapolate to past ones I have purchased, ... MoreI bought two of these.

I use my old ones in cameras now and they record 4k video with ease. Can't wait for 2TB haha, or at least 2TB in an SD card since technically it would fit.
I dont normally do reviews but this one is more about the seller Technoitems then the SanDisk 64GB extreme SD card. I had questioned the validity of the product and raised my concerns with Technoitems as I had a bad experience where the memory had been altered on an Sandisk SD card 64GB so it only recorded for 1 min 15 secs then showed as SD card fault. They were very quick to reply and assured me all are original and wanted me to try and use one to test it, If I had any problems they would sort out. I did test it I hooked up my GoPro to the mains put in the SD card and left it recording. It recorded for 4hrs 13mins 29Secs so no problem with the SD card at all. I have seen negative feedback for this seller Technoitems and its mainly for this product so I would say ... MoreI dont normally do reviews but this one is more about the seller Technoitems then the SanDisk 64GB extreme SD card.

The SD card on reverse says made in Taiwan but there was no problem recording as mentioned above. Happy with product and purchase.
I purchased this to provide an alternative boot card for my Raspberry Pi 3 Model B. The Raspberry Pi 3 kit I purchased came with a single 16 GB microSD card and I wanted another that was larger since this is the disk for a Pi. I ran down to a local store and bought a Sunpak 72-in-1 USB card reader which allowed me to do the setup with my Windows 10 desktop PC. I did use the SD adapter and the standard size SD port on the reader. Windows 10 was super easy to download the NOOBS Lite loader, extract the files from the zip downloaded, and put the files onto the microSD card. While I used the "partition" command of Windows 10 to look at the microSD card format, I did not have to make any actual changes. All I had to do was to copy the files extracted from the NOOBS ... MoreI purchased this to provide an alternative boot card for my Raspberry Pi 3 Model B.

All I had to do was to copy the files extracted from the NOOBS download to the microSD card. I swapped out the kit microSD card for this one in the Raspberry Pi and plugged in the power adapter. The Pi came up, did the NOOBS initialization, I set up the WiFi settings so the NOOBS Lite could see the internet, and did an install of Windows 10 IoT which took a while but went fine. A test program with Visual Studio 2017 Community Edition checked out so it looks like it is all golden.
