*DISCLAIMER* This video should not be seen as an endorsement by me or my sponsors of tDCS in general or the Foc.us in particular, and it is just an unboxing to showcase the product.
The Foc.us is the first consumer-grade tDCS headset on the market targeted at gamers. The theory (and there has been some research into this, but at this time many things are still unknown) is that stimulating certain parts of the brain can result in enhanced brain functionality.
Unfortunately my unit arrived damaged, but Foc.us is sending out a new one already, so I should be able to bring you my thoughts on it later.
