OBS Crius RTA Review


OBS Crius RTA Intro

Today we are going to be taking a look at the OBS Crius RTA. OBS are the makers of the T-VCT sub ohm tank, so we are looking forward to seeing just how good the Crius is and how well it stacks up against some of the other great RTA’s out there at the moment such as the Aromamizer or the Bellus.

Notable Remarks



I really like the design of the Crius RTA. It looks sleek as well as looking pretty cool and funky. I like the branding on the chimney section of the device too. I prefer that to branding on the exterior of tanks. I also love the combination of stainless steel and glass, utilising the glass drip tip to break up the SS parts of the device.

Using the OBS Crius

This tank is so so easy to use! I love the 2 post deck, making it super easy to centre your coils and making dual coils so easy to install. I always have a problem with 4 post designs and leads getting in the way when installing dual coils but with this it’s a breeze.

I also really like the amount of space on the deck, don’t get me wrong it’s nothing crazy but when comparing it to something like the goblin mini, it’s a hell of a lot easier to build on.

Another thing I’m really impressed with is the top fill, with it being a side top fill it’s so easy to fill up, easier than regular top fill devices. You simply slide the top cap up which exposes a nice big fill hole, squeeze your juice in and shut it down again. Super simple, very effective!

Juice Flow Control

I really like the idea of juice flow control, not only does it allow you to vape all kinds of juices from high PG to high VG by controlling the amount of wick exposed but it also completely stops any leaking which is huge in my opinion.

There’s nothing I hate more than coming to a tank after leaving it overnight and seeing my desk, or sometimes even my mod, completely soaked in juice. But with the Crius RTA you simply close off the juice flow and your leaking will come to an end.


Airflow on the OBS Crius is awesome too! Plenty enough for those mouth to lung inhales and with the right build you can definitely pull off a direct lung inhale. Granted it’s not as much as some of the RDA’s out there but then again this is a tank.



OBS Crius Topfill

I genuinely could not find anything that I didn’t like about this device. It’s got a great build deck, plenty of airflow, easy top filling system, juice flow control. What more do you want?

The flavour off this tank is also fantastic! Definitely up there as one of the better RTA’s I’ve used in terms of flavour. Cloud production may not be insane but it’s definitely there! You wont have any trouble blowing out some plumes with the right build in this tank.


There are only 2 things I’d really improve on this device and that is give it some bigger post holes, and a velocity style deck. I do believe they are releasing a version with the velocity style deck which will allow for even easier builds and maybe some vertical coils and even quad coil builds!

I hope the post holes are slightly larger too as you would struggle to fit claptons or any other crazy wires in this tank. But apart from those 2 tiny changes there really isn’t anything wrong with this tank.

Update (21.01.2016): I believe the V2 and V3 versions of the Crius now have larger post holes, as well as a velocity style deck, so kudos to OBS for listening to the community and making those changes so quickly.


I’m going to keep this short and sweet. If you haven’t already got an OBS Crius, go get one! It’s as simple as that. This tank is a must have for any RTA users out there and will only enhance your collection and vaping experience! If you have the patience to wait for the velocity style deck then hold out, but otherwise go and pick up one of these incredible RTA’s. If you don’t, you’re seriously missing out!
