I've got a USB F-Super that I don't use anymore, and after being confused about what it works with etc.. I'm just going to get rid of it.
So I don't really know how much these are, so I'll offer this for £10 including P&P.
I've also got a bluetooth ELM327 unit that I'm also getting rid of, as I mistakenly got this instead of a WiFi one.
PM me incase I forget to check this thread.
