kr808d-1 cartomizers
Refills avg 5 - till the filler burns
QC - a crapshoot, underfilled/overfilled common.
Cannot restuff filler
Wicks 70% of liquid before risking burn
Hard to clean - pita to dry
Refills only - no dripping
Greencig cartomizers
Refills - max unknown (150 + ? -- YMMV) - til the solder/coil snaps
QC - good
Easy restuff filler - PTB, Polyfil etc
Wicks 99% of liquid
Very easy to clean
Refills or dripping
I was worried about a ban & stocking atomizers & wanted to see how much I could push a greencig cartomizer.
I got 109 actual days of usage before I tore it apart to check condition - I wouldn't be surprised if some said it lasted a year...
Never kept score on number of refills I was more interested in coil durability, but at least 150 refills
109 days = 2.3 Ohms
Coil clean, no gunk buildup
"hair" - discolored where touching coil - very clean elsewhere
The hairs are glued to the side, there was a slight juice buildup underneath the hairs & also around the silicon +/- (probably from dripping) this could probably be avoided with better cleaning, maybe a soak instead of just a shake type cleaning.
Internals consist of coil, hair threaded through coil, plastic coil holder & battery thread - very simple compared to other atomizers.
I am very surprised that no modders have rebuilt these GC cartomizers, all I can think is that the term disposable & the price put them off experimenting. This would be the easiest to be USA produced IMO. Under extreme circumstances, I think, I could even rebuild one (no skills, bad eyesight, arthritis).
20secs burn @ 5v = the coil melted through a couple of hairs, leaving 1/8" loose strands - so clean if you accidentally burn, otherwise you could inhale those loose hairs.
Stock GC cartomizers are good but are mid TH (better than 801), you'll get better results refilling with your own liquid.
Tastier fuller/richer/heavier vapor than 510, 901
Vapor - depends on your liquid mix - good to excellent
Wicks good at 3.7v (4.24v) - too slow at 6v for a heavy user
For usage comparison - my daily use
3ml @ 3.7v
5ml @ 5v
6ml @ 6v
