OBS Crius is the latest manufactured RTA by Shenzhen OBS Technology Co.,Ltd. It has 4,2 ml liquid capacity and designed for dual coil builds. It has wide liquid feeding channels and sufficient air flow for lung pulls.
This RTA has liquid feeding adjustment capability. It can be filled from it's top-side fill hole.
OBS Crius produces top level flavour and exceptional clouds.

It comes in a quality acrylic box and has a detailed instruction manual. While a manual may not mean much for experienced users, Novice users will definately benefit from the detailed instructions in the manual.
The looks of it is very good in my opinion. You can spot the high quality workmanship in all the parts of it. It has a thick walled glass tube and also has a spare glass tube in the box.
You lift the topcap upside to reveal the liquid fill hole. After filling , you push it back down again.
While filling , you can close the liquid feeding holes by turning the tank section either way. This prevents any liquid leaks while filling the tank.
It has a wide bore glass driptip. I use a thinner one instead.
The first revision had non standart driptip size so you couldn't use any other driptips. But after the first reviewers complaints , the company fixed this issue in their later revisions.
You can disassamble the tank to its parts for cleaning.
It has 4,2 ml's of liquid capacity. Even though high liquid capacity and it's ability to work in really high wattage settings, It has a really small size. It looks very tiny near a TFV4.
Rebuilding and wicking is very easy with the Velocity style deck and it's large liquid feeding holes.
It has 2 holes per post which makes placing the coils very easy. While wicking , you place the ends of the wicks in the holes, This makes it easy to arrange the amount of wick placed in the holes . While putting the cap and the chamber on , the wicks doesn't lose their arranged shapes.
What you should be carefull about while wicking is, do not squish all the cotton in these holes.
Trim the ends of the wicks, so they lightly fill these holes. Otherwise , the liquid feeding will be limited
I use %80 VG Eliquid. At 40 watts with the air flow fully open , it gives very very good flavour and even better vapor. If you dial down the airflow to half, the flavour gets better. If you use a thin bore drip tip the flavour gets even better but the vapor production reduces. I haven't come across anything that can match OBS Crius's flavour production. This is a flavour monster.
This tank is designed to be used with higher wattages. At 20 watts it is not sufficient . At 30 watts it starts to do it's magic. Between 40 to 50 watts it is perfect , producing excellent vapour and flavour. The liquid feeding is sufficient enough even at 60 watts , not giving any dry hits while chain vaping.
OBS Crius is ahead of its competion in liquid feeding capacity with its wide liquid feeding channels. This is very usefull in higher wattage lung hit usage. But you can also use it for mouth inhale type vaping by dialing down the airflow setting and using a thin bore drip tip .
You can control the liquid feeding by turning the upper portion of the tank. You can also close the liquid feed completely to avoid leaks during filling. Just don't forget to open it again before vaping.
Half open liquid feed holes;
Fully open liquid feed holes;
The only complaint about OBS Crius might be, that it is not suitable for single coil builds. Which I don't use anyway , I only use dual coil builds.
OBS Crius had two revisions after the first version. Version 2 and 3 got updates according to reviewers complaints.
OBS Crius rev.3 is definately a winner
+excellent flavour and vapour production
+Easy to rebuild with the Velocity style deck
+Easy to wick with large wicking holes
+Suitable for higher wattage vaping with the large liquid feeding channels
+Sufficient airflow for lung hits
+Comparatively small size
-No single coil build option
OBS Crius version differences:
Ver.1 : Old style deck , tiny wire holes on posts , non standart driptip size
Ver.2 : Old style deck , larger wire holes on posts , standart driptip size
Ver.1 : New style deck "Velocity type" , two large wire holes on each post , standart driptip size
You should check for the version of OBS Crius and make sure what you get is version 3 of this atty. Efun has the latest revision 3 OBS Crius in stock.
The old version decks picture is;
Example build and wicking;
0,50mm Kanthal wire , 3mm diameter , 8 wraps. Make sure you don't squeeze too much cotton in the channels as this will negatively effect liquid feeding.
The cotton is placed, the ends are cut and then fluffed by a needle;
Very little part of the cotton is placed in the channels and the unnecessary parts are trimmed;
Wetted with eliquid and ready to go;
