This is a 4 port usb hub for no money!
Ideal for popping your laptop case to carry around with you. It includes a retractable USB cable making it easy to plug peripherals into.
Couple of caveats:
1. it is only USB 1.1, so will be slow for transfering large files.
2. You need to spend a total of £10.00 on the site before you can check out, and there is a shipping charge, not sure how this works.
However you shouldn't have any problems finding £10.00 worth of bargains!
