Well over all this product looks really great and compared to some cheap looking 2.5" drives this one does look great. However functionality wise, well I can't comment because when I came to attaching this thing to my powerbook G4, it turns out the usb port doesn't provide enough power!! After some research I found that this is a common problem and the only way to power it would be to connect the drive to 2 usb ports...however you'll know if you have a powerbook G4 that there are only 2 usb's and they are on either side of the laptop!!! Damn! So although you can pick-up USB y cables to power the thing, at the end of the day it's probably not worth it if you wanna use anything else at the same time.
My advise if your using a PC laptop, then it's a real bargin! If your using a MAC, consider getting a IOMEGA 2.5" drive that has firewire and usb, which means you'll power the thing, but have the flexibility of USB.... :)
