I meant the outer, ego threads because I usually use an evod or a protank mini on it. They wobble a little. I never tried putting a 510 head on it.
Had not noticed the EGO threads. When I first got mine I put on a beauty ring and just used the 510 threads. Tried the EVOD and there is a little wobble if it is not tightened down, which could push in the + pin if not careful. This is where the floating + pin would be nice so it could be tightened all the way down.
The post on the base is square and doesn't fit into an original Kanger evod. I'll post a pic of it some time today. When I was talking with the people at jvapes (jwraps), the owner told me that it was a redesigned evod so essentially it isn't a true kanger evod head, but like you said, it works very well.
I see what you are talking about with the square chimney. I don't have any Kanger EVOD's, mine are all no name ones, and the base does fit in mine. Mine just say "EVOD BCC" on them, no idea who makes them, but I guess they are clones or something.
I still use mine... All I do to it is dry burn and stick a piece of cotton in it and it's good for a couple more days. I'll have to try rayon soon. I've been using cotton yarn for a flavor wick for quite some time now and have been wanting to try rayon or cellucotton to see the difference in flavor. I checked out my new local store last night and the gentleman gave me some cellucotton to try out. I'm looking forward to trying this out today. I read quite a few reviews and they're all very positive.
Rayon (cellucotton) is better than cotton to me.
Long thread, but lots of good info,

There was a link in the thread to get 10' for $1.99, no freight, which is what I got. There are also plenty in the thread which have 500' boxes and offer to send you a sample. Good stuff, but you have to wick a little different than cotton, you have to use more as it does not swell when wet like cotton does. To me it does have a more neutral taste than cotton, but takes a little to figure out how much to use, too little=burnt taste, too much=choked juice flow=burnt taste.

Yes I guess I should, but it is in my hand most of the time. Late Sept when we go fishing I Will be using it, don't want to have to jump in to rescue it from the bottom of the Ocean.
