The Cruzer Micro is a USB storage device in a long line of devices in the Sandisk lineup. The capacity of the model I bought was 1 GB but there's also a 2 or 4 GB model on the market. Because of that I don't think the capacity is important in choosing (or not choosing) this product - everyone can choose how much memory they want and need.
The Cruzer Micro is small, probably smaller than your car keys or a cigaret lighter. The USB connector slides in and out of the main body, a mechanism that doesn't seem very durable to me. Another thing that can't survive very long is the little ring on the corner of the device that's just barely attached to the body. There's a metal pin to hold it in place, but it's clear that this connection can't stand up to much.
After connecting the drive to a pc you notice that it doesn't load fast at all. The embedded software automatically installs itself on a computer and you'll be bothered with a message telling you to reboot. That's not necessary though. After that it's a mystery whether or when the drive will show up in your 'my computer' screen.
If I had the choice again I wouldn't buy this drive without having seen it in action, but as it is, I just have to live with it. I'd go for a more durable looking and feeling device without unnecessary software on it.
