    I wanted a newer and faster USB flash drive to quickly copy files from my phone or laptop to my desktop. The files are mostly photos from my phone, camera or drone. This flash drive by SanDisk works very well and gives me the speed I want. I like that I can get the USB 3.1 gen 1 speed and the 128Gb size for a very reasonable price. I just plug it into my phone or laptop and it is recognized immediately. I am also able to quickly copy a lot of files to safely store them onto my Desktop PC and/or network drives. I didn't test the actual speed, but it looks like there are others that have done that here. My only concern is with the flip around cover. It seems a little flimsy and could break after a lot of uses. But, having the SanDisk 5-year warranty helps alleviate that concern. I feel this flash drive is an excellent value, especially if you can find it on sale.

    The price was great. Although I don't like having to use the app to transfer pictures or documents. It got very hot during transfers but it did work so I am happy to be able to delete some pictures and documents off my S21 ultra.

    It's small so careful not to lose it or leave it loose around pets. It works as it should and the ability to switch between USB A and USB C is very convenient when going between different devices or needing to leverage the most convenient port on your device.
