I haven't had a problem with the 100W, but do like the neatness of the NX30. The NX75 has a nice grey one but it has TC, and I'm a bit wary of TC in case I accidentally change mode and set fire to myself or some such

I have a Pico - unused and in my 'spares for a rainy day' box, but again, it has TC.
I was a bit puzzled as to why that particular 100W iStick is so cheap while all the others stay a bit more expensive - price makes it tempting. Think it's a toss up between that and the NX30.
Not that I
need one - just the magpie in me!
The batteries I have can be used in the K Box and the Sigelei Mini ..and I have spares of those too as they're quite nice to use.
Ah right - I do like one now and then, but not when (trying to) work.
I don't think I know what CCD3 is - as for tequila and lemon ..haven't had any since a very hot August in Madrid
