No problems so far
I’ve used my foc.us v1 for a few years to treat depression, and my go flow does the same job in a more convenient package at a much lower price.

Feel nothing!
First report: I plugged in this morning and hooked it up as instructed (X is on the left forehead and Y is on the right shoulder blade) then I set for 35′. By some reasons I didn’t feel anything. I then reset it to run for 5′ and I still don’t feel anything. I might have expected the tingling more than it should have been … I don’t know. I will submit my “Second” report after this 5′.

Second Report
Oops, I started to feel tingling

Again, Exceeds Expectation
only took a few minutes to get used to. Ingenious simplicity, yet powerful. It is so astonishingly good that i am almost speechless.
The real deal –
Ok but too small.
I believe the unit is too small. It definatley works but at 99 dollars I would think they would give alot extras. I will keep on using it..
Smarter? –
Don’t know?
The people writing the reviews do not seem to be any smarter?
I am definitely not any smarter after visiting the website therefore I’m not going to be ordering the product.

Where are the directions?
Hey I don’t want a LOT of instruction but telling me what X and Y mean would be fantastic.

Go Floe
My Go flow to reach me worked perfect.
Thank you very much

Very basic
The Go Flow connected to the 9V battery is very easy to use.
It remembers your last settings so if no changes its quicker to start the next session.
Instructions could be better.

Great product, super easy to use once you understand it. Also YouTube has some good videos on using this if the instruction manual gets a bit confusing.
