So... it's alive!
So far I am very happy with my DID. I haven't even gone through a full ml of juice, so I'll post more on performance later.
But it sure looks fine:
Build quality: all parts are flawless, match perfectly and the threads are smooth and noiseless. When it's fully assembled it feels compact and sturdy, unlike my other genny device. The 510 connector is good and secure, it sits almost flush on my ProVari and Legacy (without adjustments).
Ease of assembly (body): no skills job - everything only fits one way, it's basically just scewing stuff together. The smallest parts are the center post washers, but it's not that bad. I guess people with some level of dexterity impairment will have a hard time putting those on. Nothing else to say.
Ease of assembly (coil): oh, well... I'd give it a 3+/5 compared to my only other genny - a Zenesis standard. And that considering that Zenesis requires two different keys for the process. The brass nuts are a mess - you have to fiddle with the bottom one, then if you are not careful you end up moving both as you tighten the top one, then if they come together you can just unscrew the top one alone... It's a pain. But it does the job. You can't do an easy secure (i.e half loop the wire then secure it like that, such as you can do with the negative connector). You have to first fully wrap the wire around the pin then secure it
somehow.
I really like the thicker, sturdier wick though. My wick is a bit shorter than in the video, but there is no real problem gauging the length of the coil so everything goes together. I make my coils outside the device. I
think my wick touches the bottom of the tank, and it is indeed a bit annoying that I can't see it.
Once it's done, it feels secure and it doesn't seem like it's going to go anywhere, and screwing instead of snapping on the top cap also contributes tot he sturdy feeling - you don't worry you'll destroy your coil as you put the top cap on.
Performance (initial) - I made a 4 wrap coil, and got 2.1 Ohm, stable from the get-go (Jack Frost + rolling paper). It produces a very satisfactory amount of vapor starting at 5.8 Watt, then my sweet spot seems to be at 8 Watt (4.1 V on the ProVari). It's warm and thick and saturated. The wicking is extremely good, better than the Zenesis - no dry hits even without tipping it down. The vapor, so far, not fully broken in, seems very promising.
Flavor isn't fully developed yet. I'm vaping a simple Peach menthol. The menthol obviously comes through strongly, the peach is muted and there is still some add-on taste that I'm not sure where it comes from - I hope it goes away with break-in. It actually goes away at lower power so I'll keep it at that for now to break in.
It doesn't leak.
I strongly feel it would perform better with a larger airhole. I have no clue how to go about making the hole larger, but I'd actually hope Jim will consider an "open draw" cap or someone here maybe help me figure out how to drill it larger...
So that's my take so far. I am really enjoying it, and I hope it'll get much better after a couple of tankfuls.
