I just got my cartzilla from ecigexpress. It works, no issues. May have to lower from 24mg to 18 or less.
Kicks hard. Not the same as dripping on an atty, but not saying it's better or worse. No gross plastic taste (ala Tanks or Xpressomizer) For $8.99, it's definitely better than most other options.
Initially, I got a mouth full of juice and sprung a leak. Make sure the lil' rubber part is well up into the hole of the metal
bit that screws into the top. Once I got it right, no issues.
It's sold as 2.8 - 3.2 ohm; but it feels like 2.0 ohm.
