Review on Multicolored 64GB USB Flash Drives 5 Pack - K&ZZ 64GB Thumb Drive Memory Sticks for PC Laptop, USB 2.0 by Runbi Alvarez

They do exactly what they're supposed to do and they're bright colors so they're a little harder to lose. I usually buy a pack at a time because people "borrow" my empty ones and I never get them back and I tend to lose them from time to time. Bright colors make them harder to lose, but also make them more interesting to "borrow". If I run out again I will most likely buy more.
