Summary: I'll admit I mostly bought it because it was called "FireFly." I would have also purchased it if it was named "Serenity." That said, it's a good little thumb drive, although it would be extremely easy to lose if you aren't especially careful.
Summary: I've had my FireFly for two years now. I'd had a Sandisk flash drive that somehow deleted all of its files, so I was looking for a Mac compatible flash drive. My boss recommended this one. Several months ago, I accidentally washed it.
