First Impression Out Of The Box:

I always really liked the packaging that OBS uses. The Crius RDTA is no different. It comes with a black and yellow color scheme in a drawer style box with a pull tab. Once you open the box up, you see everything is laid out beautifully on one level inside the box. There is a yellow box that contains all of your spares as well as a really nice blue mini Phillips screwdriver.

As far as RDTA’s go, the tank looks to be of a common size. It’s not much bigger or much smaller than most RDTA’s are on the market today. The build quality looks to be really nice and the deck is the same exact deck as the Cheetah II RDA. I just dropped the review on that RDA so make sure you check it out.

What’s In The box:

  • One OBS Crius RDTA
  • One Mini Philips Screwdriver
  • One ULTEM Drip Tip
  • One Pair Prebuilt Clapton Coils
  • One Piece Organic Cotton
  • One Replacement Glass Section
  • Spare Part Pack

OBS Crius RDTA Review

From Top To Bottom:

The Crius RDTA comes stock with an awesome Goon drip tip. It is definitely on the short side and it is that chuff cap type of style. While the RDTA does not get particularly hot while chained vaped, I definitely would have preferred a longer drip tip just from a comfort standpoint. I also think that OBS should start including more than one drip tip in their packaging. Every other manufacturer seems to be doing so except for OBS. There is no 510 drip tip adapter which is kind of disappointing. An RDTA like this would have definitely benefited from an adapter. If you’re not going to include a second drip tip, the least you can do is put a 510 drip tip adapter in the packaging.

OBS Crius RDTA Review

The top cap on the Crius RDTA is secured to the barrel with one oring. It does have a nice tolerance on it but at first, it is on the tight side. The Goon style opening, of course, has an oring on the inside of it. The interior of the top cap itself does have a slightly conical design to it. There are only two airflow slot cutouts on the top cap so that would make the Crius RDTA a dual coil only RDTA. There is some knurling on the top of the top cap and the action on the AFC is very tight at first. I would definitely recommend that you juice up the oring and make sure you work it in there good. I would rather have a top cap that is too tight than one that is too loose. The oring definitely breaks in overtime and the AFC adjustment does become smoother.

The barrel on the RDTA has airflow slots that coincide with the airflow slots on the top cap. They are cyclops-style airflow slots and this is a side airflow RDTA. There is some type of graphics around both airflow slots. It is not offensive or obtrusive but to be honest, I could have done without it. The one thing that I do like about the barrel is there is not any gaudy type of branding on it at all. It is on the plain side but I am totally fine with that.

OBS Crius RDTA Review

The barrel is held over the deck by 2 orings on the base of the deck. In between the two o’rings, we do have a side fill port. The side fill port will accommodate most juice bottles but using the bullnose types of juice bottles or even a glass dripper could get a little messy. I really like the way they did the base of the deck on this RDTA. The part that sits above the glass is almost like its own separate RDA base. There is a negative post with a Phillips head screw. There is also a gold-plated 510 with some nice stainless steel threading around it. This part screws into an extension piece that extends the 510 all the way down to the base of the tank. The threading is very smooth and the connection that it makes is excellent. It is very well done and it makes the tank very easy to break down. I also love the wicking channel design. The wicking ports are not too big and not too small. The wicking ports measure in at 4 mm. They are just the right size for the amount of cotton you are going to use in an RDTA like this. Very well done and I am extremely impressed with the design. I love the fact that you can just shove your cotton in there without having to unscrew the base of the deck.

The glass section of this tank does hold 4 ml’s of juice. It does come off and there is a spare. The machining of the RDTA base is done very well and I really like the way they did the extension piece of the 510. It’s just too bad that they didn’t think of cutting some holes at the top of the post that the extension piece goes into. This would have made a great little squonking RDTA had OBS had the foresight to do that. Turn the base of the tank over and we have some OBS branding as well as a serial number. The 510 on the base of the tank is gold plated and so far, it has made a solid connection on all of the mods that I have used it on. The threading around the 510 is stainless steel and very smooth. I have used this RDTA on many different mods and it has stat flush on all of them.

The Deck:

This is basically the same exact deck that you will find on the OBS Cheetah 2 RDA. It is a two-post, two-terminals-per-post design. It does have that reverse style Goon clamp system on the bottom of the post. That clamp system is spring loaded and it opens up really wide to accommodate any type of flat wire build you could probably think of. Each post has a terminal on the top that measures 3 mm by 2 mm. This is basically for your round wire builds but I have been able to run flat wire builds in there while using all 4 terminals. The clamp style terminals are 3.5 mm by 2 mm. They open up extremely wide and so far, this RDTA has been a joy to build on. I really like the deck screws that were included. They are beefy Phillips head screws and the included blue screwdriver is fantastic. Overall, I’d have to say the deck is unique, extremely easy to build and wick, definitely a big win for OBS.

Building And Wicking:

This is an extremely easy deck to build on and because of the way it is configured, you can get pretty creative with it. You can run most types of coils in this RDTA and it is very forgiving as far as building and wicking goes. This deck does have 20mm of usable deck space so you do have plenty of room to run all sorts of coils. I also like the fact that the terminals allow you to put both coils in at the same time while still being able to cut your leads. Yes, sometimes you have to move a coil a little bit out of the way but for the most part, you can mount both coils and still have plenty of room to cut your leads. That is a definite pro when it comes to building on the OBS Crius RDTA. Definitely one of the easier RDTA’s on the market to build on.

Wicking is also extremely easy and I have had great success when it comes to wicking this RDTA. Of course, as normal you pull your cotton through the coil. Once your cotton is through and you have fluffed it up really well you measure your cotton up against the bottom oring of the base. Cut your cotton to where it is level with the bottom of o’ring of the base. Once that is done, you simply take your cotton and gently poke it through the wicking channels. You may see a little bit of cotton peeking out from the bottom of the deck but that is just fine. This is the best way I have found to wick this Crius RDTA. It has kept up well when chain vaping and I have not had any types of problems with dry hits at all. Wick your OBS Crius RDTA this way and you will get a really nice, saturated, flavorful vape.

How Does It Vape?

My readers have heard me say this a million times. In general, I’m really not an RDTA guy. I will say this though, I have seen a vast improvement in RDTA’s in general in the last couple of months. They have definitely gotten more flavorful, easier to build, and much more cloudy. I do like the Crius RDTA. It definitely gives you a nice, flavorful, cloudy, vape. I like the capacity that it has and I also enjoy the fact that it does very well when chain vaping. I get a very saturated, wet, cloudy, sort of vape when I use this tank. It’s definitely one of the better RDTA’s on the market in an extremely crowded subcategory. I have been enjoying my time with this RDTA. Not to the point where it has converted me into an RDTA guy but to the point where I have kept it in my rotation longer than most.

As an example, right now, I have dual twisted stainless steel coils with a 3.5 mm ID ohming out at .2 ohms at 85 watts in TC mode on one of my DNA’s. I am running a custard in it that I know extremely well. The flavor is definitely on point. I taste everything I should with the juice that I have in it. The clouds on this are fantastic and I do enjoy the smooth airflow that it has. While the airflow is smooth, sometimes, when you cut it down, you do get a bit of a slight whistle but if you make a little adjustment, the whistle kind of goes away. It’s not loud or offensive in any way, it’s just there. Besides that, the side airflow is very smooth and flavorful on this RDTA.

What Would Have Made It Better:

  • Longer drip tip
  • 510 drip tip adapter
  • A squonk pin

I think the drip tip on this RDTA should have been just a tad longer. It is definitely a little too short for my personal style of vaping. I also don’t like the fact that there is only one drip tip included in the package. If you are going to do that, then at the very least, you have to put a 510 drip tip adapter in there. The funny thing is, I think a lot of people would have gotten a lot more enjoyment out of this RDTA had they included that adapter. It would have helped in condensing the flavor before it hits the vapers mouth. So on a tank like this, a 510 drip tip adapter is a must. Because of the way they did the extension piece of the 510 pin, I think OBS should have just taken it a step further and designed this with a squonking pin with some holes on the top of the post inside the tank. We have seen this done before with other RDTA’s and I have definitely liked the way those tanks have vaped. I also appreciated the extra capacity I can have by having a squonk bottle ready underneath. I think OBS should have taken this design a step further and done that. If they would have it, it would have given them a nice little niche in a very crowded subcategory.

Conclusion:

If you are an RDTA vaper, then this is definitely one of the better ones on the market right now. It’s got really good flavor and the cloud production is just fantastic. I really like the build quality of this tank and the deck is just awesome. It is extremely easy to build on and wicking it is just a breeze. It’s really hard to find anything that I don’t really like about this RDTA. It’s a very solid performer in a very crowded marketplace. One thing’s for sure, as far as RDTA’s go, you could do a lot worse than the OBS Crius RDTA. While it may not be the absolute best RDTA on the market today, it is definitely at the top of the food chain as far as I am concerned. So if RDTA’s are your thing, definitely check one out and you will not be disappointed.
