OBS Cheetah II RDA | Hole in one (clamp on the other)

We review the Cheetah II RDA, from OBS. Wide-bore drip tip, 24 mm deck, and an innovative post system make this RDA easy to build on and a smooth operator indeed.

“New concept, new design – it’s ready to bang you all!” Umm, what…?

OBS has just released the Cheetah II RDA. This 24 mm dripper has an interesting build deck, with a hybrid post system. The split central posts are half screw, half clamp, and fastened in place with cross screws from above. The PEI (ULTEM’s cooler sister) wide-bore drip tip crowns the RDA. Two cheetah heads and the name are engraved into the side cap. Two 10 mm wide Cyclops-style insets provide airflow from the middle. The whole construction is made from 304 stainless steel, with four different finishes available. The overall look reminds us a lot of the Goon V 1.5. The Cheetah II RDA comes in two versions – 24 mm and a “mini” 22 mm edition. I’ve seen both versions selling for around $26 online.

Let’s take the Cheetah II RDA from OBS for a spin and see what all the fuss is about.

Notable Remarks

Clone or just plain coincidence?

OBS_Cheetah_II_RDA

If you look at the Cheetah II RDA and the Goon V1.5 side by side, the similarities are striking. Shorty drip tip, Cyclops-style airflow, clamp build deck – even the big cats engraved on the tank!

We’re going to put this down to coincidence, since the earliest mentions of the Cheetah II predate the Goon V1.5. And besides, OBS launched the original Cheetah RDA back in August 2016. Almost a year later, an update is well in order.

Unboxing

OBS_Cheetah_II_RDA

The Cheetah II RDA comes in high-quality packaging that’s easy on the eyes. Remove the outer sleeve to reveal the yellow box with a pull-out drawer. The RDA is inside, along with an accessories box. You get some extra o-rings, a nice cross head screwdriver, four extra post screws, a couple of Claptons and a cotton sheet.

Our samples came in gold, stainless and black. I personally like the gold version the most, because the engraving has the same color for that all-gold look.

Deck and form

OBS_Cheetah_II_RDA

The deck is 24 mm wide at the base, with a split-post build deck in the center. The build post features two 3 mm x 1.5 mm holes, while the outer two are clamps (3.5 mm x 1.5 mm). The whole deck as well as the post screws are gold-plated for the gold version, stainless for the others. The 510 pin is also gold-plated, which can be adjusted without loosening the deck. Fresh out of the box our sample wasn’t protruding enough to be hybrid-safe.

Airflow can be adjusted with the knurling on the top cap, although even juiced up it’s quite stiff. The Cheetah II RDA is only intended for dual-coil use – there’s no single coil airflow option.

A 510 drip tip is missing on this one – but I really like the 810 drip tip it comes with. It’s wide-bore, 17 mm and made of PEI, structurally similar to ULTEM. The inner chimney is curved, as is the inside of the top cap.

Set up

OBS_Cheetah_II_RDA

For this review, I used the Clapton coils and cotton included in the kit. That came to a 0.2 ohm build. I’m vaping on an e-liquid from Belfast-based Titanic Vapour, “23 Knots”. It’s a 80/20 VG/PG fruity blend with notes of pineapple, strawberry and lime with a dash of vanilla ice cream in there too. Cheers to Titanic Vapour for the sample!

How it performs

OBS_Cheetah_II_RDA

Installing the build was really easy on the Cheetah II RDA. The hole and clamp setup is large enough to get some thicker wires in there too. To install a build, you screw one lead end into the post holes. The outer posts need to be unscrewed to lower the clamps. They can only go down to the edge of the deck, so I don’t see any chance of them falling out of place. Once the second lead is in place, tighten the screw to clamp it into position.

Once everything was juiced up and good to go, I noticed that I was getting too much airflow for my preferred wattage. To vape it around 80 W, I closed off the airflow about two thirds. At this level, I can get a restricted lung hit, with plenty of flavor.

For the 0.2 ohm build, I’d say the sweet spot is 100 W and up. Completely open, it’s still too much airflow for my taste. The middle airflow ensures a leak-free vape unless you over-drip. The juice well is about 5 mm deep, so I’d feel confident dripping directly through the drip tip. Just make sure you drip enough on both sides though, as there’s no channel undercutting the posts. At their lowest point, the posts are still about 4 mm higher than the deck, so there’s not much chance for juice to flow from one side to the other.

I’ve vaped up to 150 W and the Cheetah II stays smooth throughout.

What I liked less was the airflow ring. Even with the knurling, it’s stiff and quite hard to adjust. Get some condensation between top and side caps and the fit feels even tighter. The only way I could get the top cap off was to push it out with some elbow pliers from the inside. I’m all for a snug fit, but I wonder if the color job will wear off with repeated use.

Likes

  • Interesting hybrid deck
  • Easy to build on
  • Smooth airflow and taste thanks to curved chambers
  • Loads of airflow
  • Wide-bore drip tip

Dislikes

  • Dual-airflow only
  • No 510 drip tip or adapter
  • AFC is a bit stiff (although the knurling helps)
  • No squonk pin for the squonkers

Verdict

There’s plenty to like in the Cheetah II RDA from OBS. Although it produces excellent flavor, the amount of airflow you can get makes this a respectable option for the cloudchasers too. Build quality feels excellent and I can only fault it for being a little too tight in parts.

The AFC could be easier to adjust. I was expecting it to give a little when juiced up. But at least there is some knurling – you’d be up the creek without it. And if you’re a die-hard 510 dripper or squonker, you’ll probably want to keep on browsing.

Still, the deck is an easy build and there’s plenty of space for whatever you chuck in there. The 22 mm will function the same, albeit with less real estate to play with.

I’d easily go for the 24 mm version, for the feature range, and the aesthetics – especially the gold. Recommended, if you like to drip and are looking for an easy build deck.
