These atomizers can process oils that are close to solid at room temp. I've even played with warming the oil in tank with body heat to enable the oil to adequately wet the wick then cool. It processes like a champ. It can be carbed on a regular 510 battery if you wrap plastic around the connection so you can clean it when the gas portion becomes full of condensate. Speaking of condensate, plenty of these "no-leak" designs still leak. Like most or all others, this thing will accumulate condensed oil in the gas portion of the tank that will clog it and/or leak out when it gets to flowable liquid temp and volume. Just deal with it. These things are inexpensive. I'm still hunting for the perfect vape oil setup but for a $6 glass oil refill tank that can be used on any 510 thread, this thing is a beast. Thank you yo-can.
Ok , first let me say I usually don't leave reviews of any sort but thought I needed to here. This is supposed to be the the atomizers for hive as well as Evolve units. First thing is the threads are very short so getting a proper seat is tough, second, no matter what juice I used or how careful I was with the short threads , I would get constant dry hits after a couple of draws. I left them to sit over night with juice in the upright position and no difference. Don't quite understand what the problem is but it seems like the juice just does not have enough freedom to be able to keep the wicks completely saturated. My original cartridge that came with the unit is still ok , just got the others cause I wanted to use a different juice.
