Agree that those that use tanks, standard clearo's don't need higher wattage. Variable wattage devices also have other benefits other than just higher wattage that really appeal to non-drippers. It's not just about more watts imo....This is where some people fail to do their homework , they just buy on what's popular . I got a dna 30 clone and prefer my MVP for Pro tanks , I Clears , Aerotank's etc...
DNA 30 is much better for dripper's and other higher wattage applications but imo most people who vape still prefer standard Clearos and tanks that DO NOT require high wattage.
