Clinical EEG research studies are far more accurate. I don't citations to claim that a single channel dry electrode Neurosky device doesn't compare to a high density Guger Technologies, Biosemi or a Brain Products amplifier. Of course the quality of the electrode to scalp contact makes a difference, you can't get dry electrode systems on the cheap. If you could it wouldn't be an active area of research and funding.
