I got a bunch of those blank 510 cartos back in June, and my initial impression was "Hoo-wee! Thatsa nice!" On the original fill-up, I placed 20 drops into the barrel, did a spin, and added 15 more and let it sit for an hour or so. The flavor and vapor was marvelous on a 5 volt pass-
through, and I immediately considered ordering some more.
--- HOWEVER ---
The
vape lasted about 3 hours when the taste and vapor production started to fall off, so I decided to reload. I couldn't get more than 12 drops into the barrel, and even after a spin, the filler was slushy. They'd only last about an hour from that point on, and most of them would only take 3 fills (10-12 drops) before they gave up entirely. Checking resistance on 3 of them showed 7-8 ohms after 4 uses.
Is anyone getting more life out of these?
