Seem to be clean and on the first pair, excellent flavour. I got 0.244Ω cold resistance from a pair on a DNA, which is pretty accurate once bedded in with the legs clipped. They seem to be between 3 & 3.5mm internal diameter though, which is slightly odd. Wen I ran the numbers on Steam Engine's wire wizard it reckoned they are metric sized (2*0.3mm with 0.1mm wrap with 3.25mm ID) not AWG sized, which is fine by me, but worth knowing before you buy. Exact dimensions may matter, particularly in a tight RTA chamber, and OUTSIDE diameter is 4.25mm and coil length 6.25mm, as close as I can measure. I hope this is useful to somebody, but it bears repeating that my experiance with them so far has been excellent.

It's great to be able to swap panels around to match up a mod/tank pairing. You could even use them as a replacemet in the unlikely event that you manage to damage the original ones.

Great dripper, with a range of parts to allow use of different drip-tips and the like, what's not to like?

I was bought one of these as a birthday present when I first started vaping, before I even had a mod to put it on. It's still in daily use, 8 months, countless builds, and goodness only knows how much juice later, and never a problem that wasn't my own fault when learning to wick it, so I decided to get another to share the burden. A perfect restricted direct to lung vape, with a fallback to cartridge coils if I should be unable to rebuild it for any reason. I haven't had to use a single spare part from the original set either.

Now all my toptank minis have the later (and much better) afc base :D The old style one is very stiff and difficult to operate with arthritis - I had to use one of those atomiser grippers built into the handle of some ceramic tweezers. This is completely smooth. A very worthwhile upgrade. If the lack of availability in the other original colours is a real problem for you, I guess you could paint it, although getting a match might be difficult. Luckily, the tank I wanted to upgrade was already stainless steel. The old style one will get a graceful retirement as a base for coiling and wicking RBAs for both the toptank mini and protank 4 - I know the RBA will fit straight onto a build deck, but this way I will avoid getting juice where juice should not be when priming the wick! And I'll never have to move that $%^&* AFC ring again!
