2B™

Still getting used to using the 2B, in terms of its plethora of functionality, but I've found it to be well built, and feels like it will last for a long time to come. The basic control box comes with 4 electrode pads, which work well, but I imagine it really shines when you have other types of electrode to complement the pads. Overall, very happy with my purchase, and look forward to lots of pleasurable exploration!
Some minor quibbles... The output cables that came with the 2B come out a little easily, which can interrupt your session. Also, do a bit of research to figure out what cables are compatible with what. It took me a moment to figure that out!
