I simply don't have the patience anymore to "break in" new atty's!! It just really sux.... so because of that, and the superb flavor, I've become strictly a carto user for the most part. Great at 4.5 to 5 volts!!!
Except KR's need air slots in those threads...
I've had some that wouldn't work on regular 901 adapters before.
You should be fine if it's a newer "901/KR808" adapter though. The V4L Prem. carto I'm suckin' on right now measured 2.5 ohms. Of course I'm using them at 4.5 volts too... and I love em.
That's excellent to hear!! Keep it up !!
Might I also say that you will find these a nice addition if/when you start "direct dripping"!

If you don't mind fumbing around with adapters... you might give the blank "Premium Cartos" a try from V4L. They are at least all made well/consistant, and vape great too. Just my .02 though.
I really didn't like them... they barely had any filler in them. I really don't need them anyway on my Buzz... I was just looking for something to throw on my Tornado batteries once in a while. No biggy. I'll wait till more come out and great things are said about them before I buy anymore.
