I would think about the same as the Dart... the bottom/heater is exactly the same.
It sounds like you are looking for a replacement/compliment to the omicron carts, something that will go for days without refilling, but I think you will only find that here if your tolerance is low. I see two basic rev/dart users: people with low tolerance who don't need to fully heat the unit to be satisfied, and people like me who enjoy the rev/dart for it's sheer vapor production abilities and run it at 100%.
If you don't need thick clouds, or say you are satisfied with a couple 2.4 omi cart puffs, I think you might be able to get the Rev/Dart to work for you for maybe even a whole day!
But if you have a tolerance the Rev/Dart can also be worth purchasing for their ability to quickly produce huge amounts of vapor. I like to let it get nice and hot, use reasonably large dabs that splash down onto the heater (producing intense flavor
), and draw slowly at first. When you see the vapor get as thick as milk you can draw faster, and just keep repeating that until you're happy.
That's the main benefit I see to a high-tolerance user, it will quickly get you as medicated as you can stand... but using it that way creates lots of smell, uses a lot of battery, and is not exactly something you could do in an enclosed bathroom without turning the place into a fog...
