Had this for a couple of weeks and it's a really good memory stick. Works on anything. I have windows 7 and it works straight off also PS3 and Xbox. It has a good click feature where you just push the top of it to plug it in then push it back to hide it again, so there's no loosing of lids. Also when it's plugged in, it glows an orange glow which looks pretty cool. I would say it looks the best out of all the ones out there at the moment, recommended
Got this the other day and I think it's great. It's a small fraction (1.2mm) shorter than the older microvault model and perhaps a little thinner. Also if you are concerned about size, as the USB connection pops out when you push it there is no extra length when open unlike the previous model which is the device length with the additional length of the USB connector. It's fairly fast. A 700mb file can be transferred from it to your computer at an average of 12mb/s and from your computer to the flash drive at an average rate of about 11mb/s which takes about 60 seconds or less with a USB2.0 connection. I noticed that smaller files transferred at higher speeds. The LED light is very cool. The push button mechanism is nice and it's better than the older model in that nothing protrudes from the device.
Anyway, it's really worth getting the 8gb. Hope this helps!
