I do like my mini nautilus tanks and also the MOW's, but I'm absolutely fed up of other gurgling and leaking tanks! Already binned the 30S's, about to do the same with an Aspire K1, but do still have some mini Unitanks and two mini PT2's. The mPT2's aren't too bad, but the mini Unitanks are a pain ..too much air in the draw and they gurgle/leak a lot of the time.
So, I'm keen to hear about the PT3 ...are the 3's good?
I have one standard pt3 and several minis. I've refitted them all with aerotank bases and love the result. Also, I pull the stock wicks and rewick all of the heads with cotton. Much more flavor that way.
Also have a cpl. nautilus minis and like those.
Haven't tried the K1s, but enjoy using ET-S glass tanks. Very good flavor and more capacity than either the Kanger minis, or the K1.
