Huge Bundle of 4 Snap Circuit Sets to make over 500 experiments.  Total new cost was over £200 so this is a bargain. 

Note - Set 4 shows a CD on the box, but this was not part of the set as ELENCO made the software available to download - instructions are in the manual.  

Also included is the UK mains powder adapter (cost £18.99) and a spare project base board.

Sets are complete, with manuals and all parts are working to the best of my knowledge, but i haven't used it in a few years so not 100% sure.

Spares can be ordered direct from snap circuits if anything doesn't work, but I'm pretty sure everything is ok.
