Good morning! I've been using a eLeaf iStick 30W with a 5 ml tank and Aspire coils for over two years now. I recharge my battery using a USB cable. I'm looking to upgrade my ecig vapor to a more "modern" unit as I'm having a a harder time finding coils for my current tank. Some background info on me. I'm a complete novice to vaping. I started vaping four years ago after smoking for over 30 years. I feel better and healthier using my vape. Unfortunately, my local vaping store has moved and the advice I would get from them is no longer available. My juice has between 3 mg and 6 mg of nicotine. I don't vape for the "clouds" of smoke, but for the nicotine my body still needs. I've noticed that some of the sweeter jices I've used tend to "carmelize" and turn my juice almost black, causing me to have to wash out the coil and tank. I'd like to avoid that with a new system. I am unfamiliar with the newer, more advance models and am not looking to spend hundreds of dollars on a new unit. I'd like to be in the $75 to $150 range with a 5 ml tank (min). I know most units now have a rechargeable battery system, which I am not opposed to. I try to read these reviews on ecigs and mods out there, but this is all Greek to me. I'm a newb and I admit it. I don't know the difference between the types of juices, so please don't ask me about that. I know I like an Arnold Palmer (lemonade/iced tea blend), green apple, and nothing super sweet. Can someone direct me a couple of ecigs that would fit within my requests please? Thanks!
