OBS Crius 2 Single Coil 25mm RTA

OBS presents the alternate version of the beloved Crius 2, which features a single coil only compatible build deck. The Crius 2 retains the same slide up to fill system that we are all used to but improves on the versatility of building with the new single post zirconia clamp style build deck.

The OBS Crius 2 Single Coil edition features many, if not all, similarities to the OBS Crius Dual Coil. One of the main differences would be the build deck, the Crius 2 Single Coil has a single post Zirconia clamp style build deck. This build deck can accommodate a single coil and are held down by a Zirconia clamp piece and a top mounted triangle head screwdriver. The Zirconia material has a couple of outstanding resistance varying from high-temp, corrosion, and antioxidant. Other features the Zirconia material offers is it's form factor, solid yet simple to use.  

Externally, the OBS Crius 2 utilizes the unique pull to open side fill segment, accommodating a maximum of 3.5ml of e-liquid. The fillport is designated with a small arrow located between the OBS logo. Airflow enters the Crius 2 through the bottom adjustable airflow, which measures at 12mm by 2.5mm. The airflow control ring has a double arrow design which can help users with grip. Sitting atop the Crius 2 is a 15mm bore 510 resin drip tip. The OBS Crius II is an amazing rebuildable tank atomizer to pair with a mid-wattage device due to its single coil capability.

Great Single Coil RTA

This RTA is great in every way. I vape since 2011 and this is so far the best RTA. It's easy to build, doesn't leak, gives great flavor. Just bought 2nd one for my relative :)

Best. Tank. Ever.

I own a little pile of RTAs and the OBS Crius 2, hands down, is my favorite. I've had one for over a year and it's holding up great. It's ridiculously simple to build on, equally simple to wick and the flavor...omigod...the flavor! Of all the tanks I own, the Crius 2 is the most leakproof of them all. Not a drop seeps out of this thing. Never a dry hit, either! Came to VaporDNA to get another one before they're gone forever. A great tank for new builders or anybody who loves a great direct lung hit and a solid, well-built tank.

Love It.

This is the second Crius 2 I've bought. I wore the first one out. I think that this is one of the most underrated single coil rtas out. Flavor is fantastic. Its really easy to wick. Super easy to fill. I could go on and on. If you're thinking of buying it then do so you won't be disappointed.

Works great just like the original crius did. Better than any replaceable coil tank that's for sure you can keep that lazy rich man vaping rta for life.
