OBS crius review

This is a review of the OBS Crius rebuildable tank

Note: I bought this one myself in the UK. So this is my own opinion.

This tank is fairly new at the time of this review. I primarily bought this tank since it looked interesting for topfilling and wicking. The Crius stands out from the rest due to the intuitive wicking design. Instead of holes up to the wick you are supposed to push down some wick in to the holes. And with a twist on the ring you can control the juice flow.

I have used a tank so far and I must say the flavor is very good, airflow is very good.
Compared to a Youde Zephyrus the airflow is a little bit less (perhaps 5 to 10% less)

The complete box contains a screwdriver, a spare glass, some wick (did not even bother to open it), a piece of wire, 4 pre made coils, space o-rings, spare screws and a very nice manual. The manual is very clear and well illustrated which is a nice plus

Onto the tank itself, it a very nice looking tank, seems to be well build. Unscrewing all the parts the first time took me awhile to apply enough pressure to get everything loose. I am always careful when unscrewing a new tank. I was going to try the pre made coils but directly put in a dual titanium 0,4mm (26 AWG) in, 6 wraps, coming out at 0,165 ohms. As wick I used “Fibre Freaks nr 2”. As test juice I used a 2,5mg (50pg/50VG) homebrew liquid that I currently also have in my Youde Zephyrus (coil is also almost the same). I pulled the wick through and tucked in into the holes so the holes are just filled.

I applied some juice to the wick, put the base in the tank, closed of airflow and juice flow and filled it up top. Now for filling it up you just pull the top part of the tank up and voila … you can fill it. This for me is already a must on any tank . Comparing this to other top fill tank systems (for instance lemo 2, zephyrus), this is by far the easiest system I have used. After filling it, I pushed it back down, opened up airflow and gave the juist control a twist. I started of with the holes completely aligned to the base, so the maximum. I immediately had very small air bubbles coming out which is a good thing.

So I fired it up at 27,5 J, 400F. And this tank lived up to all my expectations flavor and airflow wise. I am not a chainvaper, but it can certainly keep up the wicking. I did not do a kanthal build, since I rarely use kanthal anymore. But this tank will perform I am 100% sure of that. Personally I think this tank is more suited for the flavor chaser.

Now on the negative things … the drip tip … I have 3 drip tips that fit, all the rest do not fit.
The included drip tip certainly isn’t bad at all, but they could have made the hole standard drip tip.

Also there might be an issue if you want to use thicker wire, clapton coils, your coils of choice. The holes are tiny. So if you really like to use twisted/clapton, whatever, you might want to skip this tank or wait for a newer version if OBS decides to make the wire holes a bit larger.

Pros

  • easy to build
  • easy to wick
  • looks good
  • amazing flavor
  • very good airflow
  • comes with extra’s
  • very easy top fill
  • no leaking
  • juice control

Cons

  • tiny holes for wire
  • not all drip tips will fit

Conclusion

I am very happy I bought this one, yes the holes might be a bit tiny for some, but for me this tank is almost perfect. This tank is in my opinion beginner friendly, but building a dual coil is harder then a single coil off course.

If you like non standard dual coils, very thick wire : this is not the tank for you.
If you like dual coils, good flavor and airflow, use less thick wire : this is a must buy
