Ok. So I am fairly new to the world of vaping ( E-Cigs ). I fell in love fairly quickly but found the maintenance of clearomizers, wicks was aggravating. I was having problems with my EVOD fairly soon. I happened to walk into a smoke shop and the gentleman behind the counter recommended that I try a particular clearomizer. It had no visible wick, just a cylinder going to the top. It was easy to fill and I did not have to worry about tipping it upside down to fill it and spill it. I found it was a CE 5 wickless. For a beginner, it was unbelievable. Great Vapor, great taste, no maintenance after 3 days. Just fill and vape......WOW. Maybe I am late on this product, but it is incredible. I was getting discouraged until I found this product. Recommend it to all.
