Most cartridges are not that effective in delivering
e-liquid to the atomizer. The ways around that include:
- Use cartomizers.
- Drip directly on the atty and forget carts.
- Modify the cart filling with teabags, blue foam, et al.
- Use internal juice injection, e.g., Carlos Juice Box or MrPuffer.
If you like fiddling with things (aka modding), choose option 3. If you want full control with a PV of cylindrical size, choose option 2. No-hassle convenience, option 1. Cutting-edge vaping in a somewhat clunky package, choose option 4.
