Good day to you all, I am trying to get hold of an extra Carrera wifi hand controller for the digital set but not having any luck. 

Any recommendations? Would buying the complete set containing 2 controllers (red and yellow) and the charger station work with the two which came with the set I bought (also red and yellow) work?

I am based in the UK so would prefer a UK supplier if possible

Thanks
