Almost bought one of these yesterday for £39.99 but when I've came back on today there a little cheaper... Always a good thing :-)
At the moment I have the very similar version Lexar s23 64gb and it's awesome, really good speeds and works perfectly on my TV/Blu-ray player with MKV files. I've had other USB 3 memory stick but they lacked in speeds.
This even has Amazon Prime so you can get it delivered a lot quicker 'if' you have Prime of course lol.
