"Longevity? Look elsewhere."
I've had my Cruzer since the 2GB was $50 retail (1-2 years ago) and it's almost functionless. I used it pretty heavily, but it's no excuse for such a simple product to become defective. The slide action of the usb drive is too loose after such extensive use so that now it won't "lock" when it gets to its extended position and the resistance of pushing it into a USB port is greater than the worn down piece of plastic holding it into its extended position, meaning inserting it (its ONLY function) is difficult. In a few months time, it could be rendered impossible to use.

Let alone the software that's packaged on the drive is a huge pain. There are removal tools available on Sandisk's site, but the software itself is gimmicky at best. Sure, it's cool to have a virus scanner and Skype bootable from a flash drive, but I didn't buy a flash drive to boot things from it (although most programs will boot from one); I bought it to store files.

The push up style of USB drives is flawed. After prolonged use, the drive stops locking in its extended position, making inserting it into USB ports fairly challenging. Capped thumb have their obvious drawbacks, which leaves swivel style like 4GB Swivel Pro Flash Drive USB 2.0 with Neckstrap as one of the few long-lasting options.

"Great product AND service"
Product arrived less than a week from the day I ordered it. It was still in it's original packaging as advertised and works perfectly. I would definitely do service with this seller again.

"Use at your own risk!"
SanDisk 2 GB Cruzer Micro USB Flash Drive with U3 (SDCZ6-2048-A11)

This product automatically installs LOCKED software into every computer you use it in. I am a teacher and this software fouled the hard drive and made it more difficult time consuming, and sometimes, impossible to use other flash drives in every classroom I used it in. I have had it two weeks and I have tossed it in the garbage.
I have used other broads for years on dozes of computers with zero problems. This one spoiled four or five of my classes before I finally said, enough!

"My little Charm"
It works great. I keep it on my key chain and i love it. I recommend getting rid of the U3 on it. Kinda of a lame program.

"U3 work is not reliable"
As USB Flash Cruzer works fine. But its U3 applications are not very reliable. For, example, EverNote (Microsoft Office OneNote like program) sometimes lunches, sometimes doesn't. Seems to be, it has mind of its own to decide when to work and when don't. May be reason for it that I have Vista. Who knows? With Microsoft you never know what is compatible and what isn't. But game Atlantis works fine. (Big relief :) And its plastic body seems fragile. If you want Cruzer better buy titanium version.
