Clarity - 40Hz - Sound Player

Solid and good battery life

It's been working very well and was reasonably priced. Whether it is exactly what we need for brain theta wave therapy remains to be seen but I'm very happy with it so far.

Good value

It's a small light weight device my first impression was that it will break down easily. It's still working well so I am pleased with it.

good stuff

performs as expected, not sure about benefit
