Got mine today. It's a wonderful device. I have very much fun playing with a the settings. Thank you for your work Imeo! And don't forget, to tell all the people who are involved in its production and assembling, what a great work they have done for us. I started with a dual coil 1.0 Ohm. That of course is better than anything else i vaped so far. But i think i can go down to .8 Ohm. That's to low for the provari, but the GGTS can handle this.
