Have had the Rose2 down to 0.20 ohms, and she was ok, have both at 0.42 ohm's and vaping at 72 watts without a problem, do have the ac rings removed, and thinking of drilling out the air hole a tad on one. But yeah, can handle 0.7 ohms without breaking a sweat.
Sweet! I think I am going to grab one.....If it will run well on a mech then I'm all in!!
It does seem like an ingenious design for sure. I am excited to give one a go!!
