I use Kanger cartos (808's and 510's) exclusively now.....since you can't really clean the Boge and Smoktech Vertical Coils.
You pull polyfill out with tweezers, rinse, blot dry with a paper towel. Dry burn coil about 20 pulses until no smoke (gunk). Rewrap polyfill around a coffee stirrer straw (fits perfectly over the air tube) and return polyfill into carto.
You can clean and dry a carto in under a minute. Works great on all horizontal coil cartos including Smokeless Image. I just prefer a 2.0 LR carto myself.
