It looks to me like a fancy TENS unit...but it also uses laser therapy. I've heard people talk about that on here...only I can't remember what they say about it. But I bet if you do a search you can find some threads on it. If it works...may be worth a shot...but that's a lot of money.

Did you find what you were looking for about tDCS? Remember that the unit is not a tDCS machine but actually an iontophoresis unit and the most common one that I think most of us were using is the Activa Dose II. Some sites require a script from a doctor...others do not. The tDCS unit is the biggest cost...between $250-$300 usually...but you'll also need to get TENS wires and the sponge electrodes to convert it for tDCS therapy. All together it cost me about $300.
