The deadline for receiving comments will be 23.59 (BST) on Wednesday 17th August.
I will randomly draw a winner from a list of those who have submitted a comment. It doesn't matter if you are the first of last to submit a comment, I will export all names and make the random selection outside of the comments sequence.
On Thursday 18th August I will announce the winner. You should watch for this announcement (across all my outlets) and if you are lucky to win, send me your delivery details and I'll get the device in the post to you ASAP. It doesn't matter where in the world you live, everyone is welcome to take part.
