    This flash drive like almost all others works fine. It is fast (USB 3.0) and reliable. It is not as small as some, but that means it is easier to find. I always connect a lanyard to them so they don't get lost. On sale, great price.

    This flash drive is perfect for my needs. I've moved several of my folders onto it to either save or put on lap top. Perfect for my needs, and now I don't have to worry about my computer crashing and losing my folders.

    I bought three of these SanDisk flash drives for back-up instead of paying for more iCloud memory. They're very fast and work flawlessly.

    Got this on sale while visiting daughter in Atlanta - needed a hi-capacity flash drive and got 64gb for price of 32. What else can one say - it works, SanDisk is almost always good stuff, and Best Buy had it on sale. A+

    This drive fits great into my laptop. Some are pretty tight and I swear I am going to break the USB port trying to use the drive. No worries with this one. The retracting interface and lanyard hole are also pretty helpful.
