Speaking about cart I got the chance to test the full ceramic Duocore cartridge by Ispire and they are great, airflow is better than Ccell although you can go faster through the cart if you are pulling too hard.
I'm working myself in a dusty environment and I would dig a cart battery where you can seal all the cart into the battery, with the one I have (Uni pro, Handy, Ispire autodraw battery and small pen shaped batteries) I always got contact issues cause the dust, dust in the mouthpiece also... I use silicone caps for the mp but they tend to slip out and last trick is to put the battery in a small box but it's less easy to grab for a hit. I like these catridges for daytime use, faster to get a hit, stealthier and since I fill my cart myself for the most I do low thc load mixing my wax with some cbd wax (or sometimes with cbd e-liquid booster) to lower thc wax content to a 50% level making hits less potent for working time. I still have a Uni Pro with a full cbd extract cart ( Grow carts by the-best-of-nature.com
), taste very good since terpènes are extracted from cannabis, surprisingly uplifted also!
Do you have a link for the Shiv?
