So learning experience.
I bought some cheap aliexpress carts just to see if they worked or were crap, labeled as cc-ell at about $13cnd for 10 essentially the cheapest glass/metal ones you can get.
Did they work sure, except every one that was filled leaked through the coil and down the main air hole either out the top or bottom or both with storage where as legit CCell , verified and some generic ceramics i had all were fine when stored right beside them.
So likely a wick /airspace gap or just design issue.
i’ll included a listing photo below but ill be likely trying out some other cheapies in the future but will likely avoid all the barebone basic ones like below.
Also have some cheap aliexpress ceramics ive been playing with that are holding up for now they just have a very loose/movable center connection pin vs better legit brands.
