I won this RDA in a Heaven Gifts giveaway and received it within a few days – thank you to HG. Life got in the way, but I finally have some breathing room, so here are my thoughts on the atomiser.
What you get
It comes in a standard box, with a scratch and sniff authenticity code. Inside is the RDA itself, along with a mini-bag of cotton. There’s also a bag of spares – allen key, 2 o-rings, a few spare screws and a squonk pin. It doesn’t come with a drip tip, but you can install your own standard 510 tips on the cap.

First impressions
The Wasp is nice and small with a diameter of 22mm. I got the gold plated deck version, and a very orangey Ultem top cap. Quality is really good. It feels really solid, all the threads and finishes are smooth and there was no oil, burrs or bumps on the machining.
Next, the looks. Totally subjective, but the way this looks is everything I don’t like. I can’t stand blingy gold, and I can’t stand the cigarette-stained plastic look of Ultem. The overall design is pretty attractive, it’s just the materials and finishes which are not to my taste. I’d love it if Oumier would bring out some black, white, frosted or glass topcaps. It would take this RDA to another level.
It doesn’t look good on every mod. Being quite a curvy RDA, it actually needs to sit on a curvy mod.
Here it is on a couple of angular mods. On the Limo and Halcyon, it just looks like a barnacle stuck on a box.

A bit better on the Pico squeeze.

With added curves - Wasp on the Gloom FTW!

Setting up
The RDA comes with the non-squonk pin installed. It was a battle to get the standard 510 unscrewed. You have to take a hefty screwdriver to it, and apply a lot of pressure. With a bit of elbow grease, it’s possible to get the pin out, and the squonk pin screws in very easily.
The 510 pin seems to protrude a fair amount, but I would not presume whether or not it’s hybrid-safe as I’m not knowledgeable on the topic. Here's a pic so the experts can decide.

The o-rings on this little guy have the perfect amount of tension. It’s easy to take the cap on and off, but it sits snugly once installed. The cap turns smoothly when you want to adjust airflow – much more so than many pricier RDAs.
Building and wicking
The deck is gold plated, 2 post and has a reduced chamber. It’s single coil only, with air hitting the coil from 2 sides. The airholes are a decent size – about 5mm wide. Build space is decent. I managed to get a 4mm ID build in with no problem, so using smaller fancy coils should be no problem.

Building is a breeze. Just stick your coil legs in the hole and tighten the posts down. Then snip off as close as possible to the deck.
I went with a 24g stainless steel coil, 8 wraps around a 4mm post, which came in at 0.44 ohms. I put my coil in upside down, so that the air hits the coil directly. A quick dry burn and on to wicking, which is a piece of cake. Organic cotton, Scottish rolled and tucked down – done in 30 seconds.

Vaping it
Right. My first go was with air wide-open, no drip tip, on a mech squonker. Air is big on this, as is flavour. But it was a bit too much. With the coils being less than a centimetre away from my mouth, the amount of airflow and heat felt like I was inhaling molten lava.
Adjustments made. Most drip tip look daft on this atomiser. I would have really liked to have a rounded, stumpy 510 tip to hand, but seeing as I don’t have any, this was about the best I could get. It makes a big difference and allowed me to actually appreciate the vape on this.

With airflow wide open, you get a very airy and pretty flavourful direct lung vape. Halfway closed, flavour improves somewhat, but the air is hardly reduced. I ended up with the airholes closed about two thirds and wow. You still get a lot of air. It’s a barely restrictive lung hit, but the flavour goes through the roof on this setting. Vapour is much more dense, and so tasty. It almost feels like you are drinking the juice. For me, this is the perfect vape.
I don’t think you can really mouth to lung with this atty. Even on the tiniest air setting, you are getting a tornado of flavour and air into your mouthhole.
The squonking action works really well, and with side airflow, I have not had one bit of leaking, even when I was a tad aggressive with the squonk action.
TL DR
The Wasp Nano leaves me in a dilemma. I think it looks terrible. I love the way it vapes. It is awesome, and outperforms all my other attys. There, I said it. Vape on the Wasp Nano, and then follow it up with any other RDA, RTA or RDTA, and they taste insipid and weak.
It is one of those RDAs which come with no hype, a cheap price tag and few expectations. And then it goes and blows your mind by delivering a fantastic experience. I will be holding on to this for sure.
Really, as long as I don’t really look at it, I don’t have any negatives to report. I’m actually taken aback with how much I love it. I’ll be keeping an eagle eye out for more colour options, because a black or glass one will just tip it over into perfection. Please Oumier, do it.
Thanks for looking, and a big thanks to Heaven Gifts for sending it to me.
