Got my first IBTanked and Loki Ring late yesterday... from order to receipt was faster than expected, only 3 days. This is also my first carto tank ever. I am not a fan of carto's is why.
First Impression of the tank... the painted bold black swirl is not done well at all (in fact poorly done). Has lines that are not even close to parallel, lines that almost disappear and then restart - so no consistency. I turned out the best side for the picture, but even there you can see one of the the line spacing issues where two run closer together and then back out. Some might call it individual flare... I call it sloppy work. Other than that it looks to be a pretty solid tank.
The Loki ring is loose as a goose with the tank in snug. But I don't see that as a problem. It sure mates up the tank and device nicely.
I bought the wrong cartos from them though. Saw many comments by folks favoring single coil and flanged for them... then after I ordered saw comments favoring dual coil and unflanged. So what I got was 10 single coil flanged 3.0 ohm with two micro holes (since I don't have a carto punch yet and the one they sell is out of stock). After set up and filled it was a no brainer that the micro holes didn't work for me at all, but an ice pick and hammer did.
Refilled it with my White Lightning, now it draws great. Muted as all carto's are to me, but the carto tank idea is growing on me as I get used to it. It's going to work out fine... I'll make some stronger flavored DYI for them. I don't want to put anything SS, Chrome etc on the Stealth or the Military. I am going to order another tube for this IBT though, probably the Abyss that is all opaque black that is hopefully consistent. And I'll get some carto's without flanges, maybe try some dual coil as well.
Already had 4 other carto tanks being discussed with other vendors, two of them custom, but ordered the IBT for something to use until they fly.
Here's a quick picture of the IBT/Loki on the Sealth Mini with its extension cap and the custom wire mesh drip tip I got for it. The point and shoot doesn't do very good pictures though.
