I agree. SMOK can be pretty crappy at times. The tanks all leak, I always get some juice in my mouth when vaping big clouds and my gx 350 mod almost burned my house down because the fire button did not come all the way out when I put it down so it just kept burning the coil even when I was not using it. I steer clear of SMOK as much as I can. WISMEC is much better imo.they all look ok but personally i would stay clear of smok as they may look good but their qulity control and coils are crap.
also the smok is a direct to lung cloud beast compared to the other two.
