Put a 2ohm LR510 carto on the Darwin yesterday, filled initially using condom method, pulled the rings off and put on a drip tip. When the vape and or flavor started to taper off, I'd pull the DT and give it 3-5 drops of juice to top it off and wait for a couple of minutes to let it soak.
Wife and I are on a ultra low calorie HCG diet, and the actual diet part of it started yesterday. Chocolate e-juice on this setup probably saved our

. Getting off of the sugar and other crap made each vape taste like a veritable chocolate symphony. The last couple of weeks I've been really leaning towards various analog flavors, but right now every cell in my brain is screaming for sweet flavors (along with nicotine). In his supplier post, Drew talked about 'vaping like a research monkey' on the Darwin, but my wife and I actually depleted the battery in 14 hours.

The Darwin promptly shut off, and the Evolv atom display was replaced with an empty battery signal. Friends in a social gathering, mostly females, helped when they found out about the juice flavor.
<looks around to make sure wife is still asleep> Guys, when it comes to breaking the ice with women who smoke and/or vape, a good chocolate ejuice probably ranks up there with carrying a small infant or a tiny, fluffy puppy...just try to ensure you use the Darwin's powers for good rather than evil.
I'm really liking the LR510 carto between 8.5 and 10 watts, depending on how long of an inhale I want. It produces huge plumes of slightly less dense and cooler, but tasty, vape. I'm going to see how many days of this abuse the carto can take. If it will last for two days or more, it's daily cost of use will be one dollar or less, which counts as a decent value in my book. I'm also liking the lessened frequency of dripping with the carto as opposed to the LR510 attys.
When this 510 carto gives up the ghost and shuffles off its (heating) coil, I'll move on to 901 attys and KR808D-1 cartos. But you can rest assured I'll be coming back to this setup on a regular basis.
