So I just came across this and I got one. Basically not a lot of people will need this or might find this useful but it will definitely save those who have a use for it ££s. RRP of these things on Amazon and Ebay are very marked up. Why not save some spare money and get one second hand for a fraction of the cost.
I got mine from my local CEX store, its showing as in stock online as 23 at time of posting with select stores having 1 or 2 in stock. Hope it helps someone.
NOTE these are secondhand but got mine and it you can't really tell, perfect working condition.
