So after reading about how amazing they are, watching reviews about how amazing they are, I was sold. My first venture into the clearo world, and my first into the syringe world. Got myself a pack of 5 2.4-2.6 ohms. Filled my first one, and it only worked at 3.2-3.4 Volts -_-. Anything higher and I got a burnt taste or dry hit. Tried 4 different juices on it with the same results. vaping at such a low voltage was okay, but nothing near as good as 3.7 and up. Filled my second one, and it was a godsend. Vaped all day at 4 volts and vapor, throat hit, and flavor was incredible! At 4.2 volts I started to get a very slight burnt taste, but it was rockin so well at 4 volts that I was completely satisfied leaving it at 4 volts. In fact, it was so amazing to me that I decided to order 2 of the 3ml version (I hate constantly refilling cartos). I figured that first one was just a one time dud I got. Filled my 3rd one last night, and it was god awful! No matter the voltage, I got a rancid, sweaty smelly sock taste that made me sick. I took it to work with me and didnt bring any backups, so I was forced to go more than half the day without my nic fix, and almost bought a pack of cigarettes on my lunch break. I decided against getting the cigs, but I didn't want to waste my juice, so I begrugingly cranked my Twist all the way up to 4.8 volts to intentionally get the burnt taste, so that it could counter act some of that horrid sweaty sock taste. I vaped through about half the carto, and noticed that the sock taste was diminishing. I turned it back down to 4 volts, and all of a sudden that awful sock taste was pretty much gone. I've now been vaping at 4 volts for the past hour, and the flavor is decent (i still get a very faint sock taste once in a while). So this has been a pretty odd, frustrating and annoying experience. Anyone have any idea what the heck is going on? Anyone experience anything similar? I'm going to refill that 2nd phoenix later tonight and see if it performs well again.
