Hi, I've been vaping a month now with a ego pen style starter kit. I want a better vape but don't want to spend an arm and a leg...Just yet. I've been looking at the vision spinner with the variable wattage. I like the clearomiser because I can see how much juice is in there. I also want something small and comfortable in my hand. These vision spinners are inexpensive. But are they worth buying for my next set up?
