I've used so many different types of Atty's and Carto's. I thought I found what I would stick with the SmokTech XL dual coil Cart and used them for over a year. Glad I switched to the DCT. It allows for more cart options and I can always see the level of juice in the tank. Provides a lot of warm vapor. Can't wait to try my triple punched 1.5 dual coil's!
