Strong work on the vape tank setup there
@Vape Donkey 650 ! Gonna have to try that out myself. I've got a cubis pro mini that I don't really use, just gotta pick up one of those RBA coils & some CO2 oil.
I've been using my v3 quite a bit & really put it through it's paces recently taking it to some phish shows & letting a bunch of friends try it out. Gave pretty minimal instruction, just told people to hold it upright & draw slowly. Everyone liked it a lot & no one (even vape naive combusters) had much difficulty using it.
Finally broke it down for cleaning, probably had close to 1/5th a gram of reclaim down there lol. Haven't really had any leakage with the 2.x, but I use it quite differently than I do the v3. It definitely seems to perform better once the post holes get a little gooped up as previously mentioned. And after a while it does seem to accumulate enough reclaim under the donut to provide a copious amount of reclaim hits. I usually don't do that, but these were still pretty tasty, to a point. I think the way the airflow is set up causes it to cool much more quickly (especially if you continue to draw after you've let off the button) & thus doesn't taste all funky until you really gunk it up.
Disassembly & cleaning was pretty easy, just took it apart & did an overnight iso soak, then hot water rinse. This got most everything off of the mouthpiece and housing, still had to use an alcohol wipe to get a few stubborn bits off though. Hooked up the donut to the base sans cup to burn off the remnants & it now looks as good as new. Burned it clean on 16.5w on my minivolt that I pretty much exclusively use as an ohm meter & for burn offs these days. Thought I'd have to crank the wattage higher (I use 27-28w in TC mode) but was able to get it glowing orange at 16.5 with a little effort. Gotta torch the cup when I get home & will reassemble. No resistance change in the donut post cleaning though.
I'm really excited to try the medium donuts, and may pick up a black v3 as well. Really like this a lot. My only gripes would be the amount of wax that makes it's way down into the base & posts, and having to use the screwdriver to remove the base. If I had a more stable concentrate I'm pretty sure I could load it by just removing the mouthpiece, but this PHO is sticky as fuck lol. The blackberry kush wax is a little easier to deal with, will try & load some of that with one of the included silicon tipped dab tools with the base still attached tonight, don't think it'll be too difficult.
I also think a hydratube of some sort would be great! Although it hits really smoothly at the temps I'm running now (28w, 380F, TCR=245 on a vtc basic). Easily the best wax vape piece I've tried!
Can anyone comoment on the difference between the v3 and v2.5.. especially on the leaking
The main difference is the donut size. Significantly larger on the v3, though different sized donuts will be available soon. The v3 is also able to be fully disassembled, which makes getting it "like new" clean is now possible. W/R/T leakage, the only way I've ever had a v2.x leak was if I overloaded it & some wax climbed up the side & into the airflow holes & then down the base to the 510 pin, and that only has happened once or twice. The v3 has airflow & wire lead holes in the bottom of the cup so some concentrate is almost certainly going to get down there every time. However this isn't as much as a problem as it would seem. The v3 functions a little better when some gets down into the wire lead holes, and the leakage from the airflow holes isn't that bad and can be mitigated with cool down hits (though perhaps putting the hole in a convex dimple could reduce this?). Hope that helps!
