I had the same problem with some Boge 2.0 ohm cartos in the past (will never use them ever again!). Except those wouldn't even absorb 100% PG liquid! Ever since I found the 1.7ohm Resurrectors at CCV (crystal clear vaping) I never went back to any of the sub-par cartos. They hold 1.6ml, last a very long time, are 15 cartos for $20 shipped with the coupon, you get a free drip tip with every 15-pack order and crystal clear is the only place that gaurantees their cartos (I've had a couple dead ones and they shipped replacements immediately!)
Oh yeah, back to my point, with the Resurrectors, I don't have to add anything to my Boba's and Gorilla Juice AT ALL! They suck the juice right up and vape perfectly with no burnt taste at all. Do yourself a favor and buy some now!
