To understand, you have to try this and that. Of course, it very gently works for meditation very well (although some find it boring). On the other hand, don't always want to meditate, and sometimes you need to cheer up, and even to have fun, then against the rectangle of the sine of taxis.

Innerpulse (by the way, where sine is also possible to include) is also good because it has the function of audiostrobe decoder and there you can download additional session, which in Lum are not. But the effectiveness of these devices is the same.
As for the points, then, in my opinion really standard points is enough in terms of efficiency (for example, I have 10 years in with the standard red), but again, the entertainment component with ultra-white or red-blue (red-green) glasses much better, and allows Colortrac else to do, and color therapy...
