It doesn't get better than this.
A very good card, from a reliable manufacturer and a great play.com price. Unless you have a REALLY high end dSLR (like the Canon 1-D series?), the read and writing speed (~ x133) of this card will be faster that your camera can cope with - so you will know you are getting the best performance from both ......
You will of course, notice an improvement in speed if you use a card reader to transfer your images or files.
Also comes with Sandisk Rescue software, a serial number for a light version of the PhaseOne 'Capture One' RAW image converter program and a wee soft padded 'neoprene' type pouch (for 2 cards)
Free P&P too - so why bother with the High St or dubious online sites?
It's a 'no brainer' - just buy one.
