Hello!

The Brain Salon is the sister product of BrainEv. It comes from the same group of developers, with connections between the two. So if one program works well for you, you'll probably find that they both do.
We let our list know about the Sonic Vitamins range, because we think it's relevant. Although developed by another company, I know the individuals involved and actually oversaw much of the original development of these sessions, so can vouch for their efficacy.
The difference is that the Brain Salon is a handful of sessions, designed for very specific purposes. There are six sessions in total, each lasting 30 minutes.
Sonic Vitamins however is a wider ranging collection of sections. I believe there are around fifteen sessions, and various 'packs', all lasting for varying lengths of time.
So... both work, both are good programs... it just depends which you think best fit your need.
Thanks!
Karl
