Mine came in today from Triangle, and did my first build on it. Only been through half a tank on that initial build, so my impressions are just preliminary/subject to revision.
Positives:
1. Same excellent build quality and packaging as every other UD product. I have about a dozen of their tanks and drippers, and have always been impressed with what they deliver for the money.
2. The airflow is excellent. Wide open it’s a cloud maker on the order of a wide open dripper. Even with it half closed I can still get a good lung hit. Most ample airflow I’ve ever encountered in a tank.
3. Bottom fill screw is easy to remove (it is more like a threaded plug than a screw).
4. Very compact size. Nice clean lines that looks good on pretty much everything.
5. Post holes are nicely sized, and the screws hold the wire very well without cutting it.
6. No dry hits, leaking or flooding. I’m using my current favorite cotton (Fantasea) on a 0.5ohm build. Not a fussy tank when it comes to wick placement.
Minuses:
1. Post screws are tiny. I can see the heads stripping after a lot of use. You get a spare in the spares kit, but only one.
2. Build deck is cramped. Had to yank out my first build since I made the coils 2.5mm, which is too fat to fit between the post and the chimney wall. 2mm fits; 1.5 would be better. The cramped deck gives me pause to try this with a Ni200 build.
3. Glass is just a little bit smaller than the T5 and T7 glass. I think the glass will be interchangeable since it’s floating on o-rings (usual UD design) but need to test it to see if it leaks.
4. Flavor so far is decent but not outstanding. But, need to try a few other builds before I can say that for sure, however.
5. Lots of crackling! It’s one of the noisier tanks I’ve used.
6. Fill hole is small, so you have to use a syringe with a thin needle to let air escape. Even so, you have to fill it slowly.
Overall: well worth the money, and I’m looking forward to trying out different builds and wicks with it. Look forward to others' impressions.
