I ordered the DIY 4 Star General and mixed at the recommended 6% and 70/30 Pg/Vg. It's been 8 days and it is ready to vape. As we all know it only gets better with time. I had a hard time paying $24.95 for a 10ml bottle. I made 2 60ml bottles with plenty left. IMO it was worth the money. It is by far one of the best RY4 on the planet.
