I bought this to use in a mini camera that I use for security in my bedroom. Before I bought this SD card, I had a 2GB micro-SD card, but the 2GB storage would quickly full up because the camera was motion sensitive, and would track my cat as she jumped on and off my bed. I needed a bigger card, but the camera only had a micro-SD card slot. This fit the bill. The SD card is compatible with my camera, and it doesn't fill up even if I am gone for a double shift (which is more than 15 hours day) without checking and emptying the card. The card also is universally readable. I primarily use my micro-SD thumb drive (see photo) to read and erase it, but I have also put it in my SanDisk micro-SD to SD chip, which can be read on the side of my MacBook. With the true capacity at about 64 GB and the price, I am very happy that I bought this!
Frankly I'm amazed that cards have gotten so cheap throughout the years. This price is amazing for 64gbs. I have it in my WYZE camera and it records HD video and audio. I was really worried because the last few SD cards I had bought in stores were corrupting but this one is very well made. I'm never buying an SD card in a store again. Not to mention it's like twice the price in the store. Great price, great value.
Got this memory card to use with a 4K dash cam where a 128GB is the largest capacity card it would take. This has been in use constantly in the camera as I normally don't turn it off so it is constantly recording & wiping out the oldest as each new 10 minute clip is captured. I have not had any issues with a bad file.
