gvg is the way to go.  save your pennies, i only make a very small amount of money---  I tried all of the inexpensive ways, I do mean ALL.  but in the interest of not wasting my precious time and in the long run not wasting my precious money, I saved up and got the gvg. and it is priceless. 

I also consider engaging others in this incredible medicine is important and a modern shamanistic healing device. 

Also-In the interest of sharing and not making those we share with feel sketchy, get gvg.

Love
