There are a bunch. Good Starter Setups for a Beginner Vaper
Sorry to say, but your current setup is quite archaic and primitive. Stuff we had to use 10 years ago. An anology would be cooking on a campfire as opposed to cooking on a gas stove. The real simple setups work for some folks, but if they don't you don't have options to improve your vape.
Technology has improved immensely since then. You need a mod setup that is variable wattage, a tank that has adjustable air flow and coil options with more than just one coil resistance (ohms). Having the ability to change your wattage settings and adjust airflow settings is a game changer.
You'll be surprised to find that beingable to adjust the air flow or changing the heat of the coil higher or lower can make a huge difference in your vaping experience.
Yeah, I mean I've stuck to this because it's simple. I've never been interested in modding because I'm not looking for a "toy." I just want a simple replacement for a cigarette.
