The 'g' is basically the same as the 'c' model except the lead is a bit shorter. This is the 'g' version and is black.
I know this has been cheaper on amazon but its not anymore and this is the cheapest Ive seen it recently. Seems like a good deal to me.
The attached 5% voucher (AMP3MVC) worked for me but a more recently posted one didn't. Don't forget 4% quidco making this around £56.07!
First deal post!
