OVVIO X2 Review: Pre-Filled Pods with μKERA Technology

June 25, 2020

Product intro and specs

The OVVIO company is a new addition to the vape industry. The X2 is their newest offering, and the first product we have tested by them. One of the standout features of this vape is the integration of a new ceramic heating system called μKERA, developed by the JWEI company, which utilizes a refined porous ceramic material.

The X2 is a pocketable and lightweight beginner vape with a simplistic design that is available in black, gunmetal, and red. It’s draw-activated and there are no buttons or screens to deal with. The X2 runs on 1.5 mL pre-filled pods containing 5% nicotine salt. The pods drop right in to the device and are secured magnetically. They are sold separately in packs of four and there are currently six flavors to choose from.

The X2 was sent courtesy of OVVIO for the purpose of this review. There are no shops that currently have it in stock, but we will update this review when it is available for purchase.

Size, weight, and feel

The X2 weighs about 28 grams with a full pod installed, which is pretty light. It stands at about 106.6 mm tall, 19 mm in width, and 11.5 mm thick. The design is on par with the latest wave of pre-filled pod vapes like the RELX Classic for example. It slips easily into your pocket and can be concealed in your palm while hitting it, which will probably satisfy the stealthiest of vapers.

The device is constructed of aluminum and has an attractive matte finish, which provides a nice contrast against the shiny mouthpiece of the pods. The build quality seems to be pretty rugged, especially for such a lightweight device. The bottom of the device is curved, so it doesn’t stand upright. Other than that, it’s just a solid little device with a sleek and minimalist design.

The pods have a dark tint to them, which is annoying, but you can still check your liquid levels by turning the X2 upside down in a well-lit area. As long as there is a little bit of juice in the pod, you can vape it down to the last drop. It seems like the longevity of the heating element generally exceeds the liquid capacity. Only one of the pods I received didn’t make it to that point.

Getting started

The X2 battery comes with a USB-C charging cable, a user manual, and a small brochure with a bit of additional information about the μKERA technology. There’s nothing else needed really, as this is super-easy to use straight out of the box as long as you have some pods.

The X2 is a draw-activated vape, so the only thing you really have to worry about is making sure it’s charged. You won’t need to turn it on and off, or learn how to adjust anything. All you really need to do is pop one pod in, and inhale. That’s it!

How does it hit?

The X2 provides a stiff draw with a nice amount of resistance to it. I think it would be suitable for smokers looking for a seamless transition into vaping, especially using the tobacco flavor. I can also see it being popular with the MTL crowd because it has a real-deal cigarette-style draw.

The throat hit is satisfying, even though it’s actually on the smoother side for a 50 mg nic salt pod. I don’t get a dry or scratchy feeling from it, which has typically been my experience with vapes that utilize ceramic coils. There is a slight hint of ceramic taste, but the hit it provides outweighs that for me.

I’ve gone through a bunch of full pods already and I have been impressed with the lack of any popping, spitting, leaking or gurgling. Out of the six flavors I’ve tried so far, I did get a few dry hits from one of the grapefruit pods. It wasn’t a regular occurrence, but worth pointing out. Overall, the puffs were very smooth and consistent. I wouldn’t consider the vapor temperature to be particularly warm, but it provides a nice dense hit that I can enjoy.

Are the flavors any good?

There are currently six flavors available for the X2. Three of them are fruit-based with a slight cooling effect. The non-fruity varieties are the mint, tobacco, and mint tobacco pods. Each one has a different color on the base of the pod that corresponds to that particular flavor. The pods are currently available in 2% and 5% nicotine salt.

I wasn’t exactly blown away by the flavors, but the overall quality seems to be alright for this style of vape. All of the icy flavors start to become a blur at some point. One flavor that really stood out from the rest was the tobacco flavor, for reasons that you might not expect.

Tobacco: This was the only flavor out of the line that doesn’t have a cooling effect. That wasn’t the big shocker, this flavor is a trip! It reminds me more of a cigarette (somewhere between a Parliament and a Marlboro) than a tobacco flavor. I tend to enjoy the smoother RY4-style tobaccos, but this would be a great flavor for people who want something with an authentic tobacco taste that is reminiscent of smoking.

Mint: This flavor is more of a sweet mint than a menthol flavor. It almost reminds me of spearmint gum. There is a nice amount of sweetness to it, but not too much. It’s a tasty and refreshing flavor that would probably satisfy people looking for an alternative to cool mint JUUL pods. This was one of my favorites of the six because it is simple and satisfying—although one of the mint pods failed on me before it was done and I’m exactly not sure why.

Mint Tobacco: This was yet another flavor that threw me for a loop. It would be logical to assume that it tastes like a combination of their mint and tobacco pod flavors. Wrong! This flavor actually has a bit of creaminess combined with a minty and slightly cool finish. It doesn’t have too much of a tobacco taste, it’s very subtle and way smoother than their tobacco pods. I almost had to do a double take to see if it was supposed to be a custard flavor. If you want a rich and creamy mint tobacco, you’ll enjoy this one. I happen to enjoy this one a lot, even though it’s hardly a tobacco flavor.

Mango: I enjoyed their take on this popular pod flavor even though it’s a bit too sweet for my preference. It does have a pleasant mango nectar taste going on. I would compare it to the mango e-liquid by Pod Juice, rather than the JUUL version. It really leaves that icy effect that you’ll notice, especially after drinking cold water.

Grapefruit: I like grapefruits, but I’ve yet to have an e-liquid that captures that tangy and bitter citrus taste. This flavor comes somewhat close, but there’s something weird going on, possibly due to the cooling effect or the ceramic heating system. The flavor actually tastes like gasoline to me, with a sweet citrus taste that almost saves it. I was still able to finish the pod, but it happened to be my least favorite out of the lineup.

Blueberry: This flavor was confusing. It says blueberry, but the picture on the pack looks like a bunch of purple grapes. I think they should have gone with a dark blue color instead (to differentiate them from their mint pods.) The flavor is also pretty ambiguous. It might just be the placebo effect from the packaging, but I kept forgetting that it was supposed to taste like blueberry. It just reminds me of a general fruity candy flavor with a hint of cooling. Is it blueberry? is it grape? Your guess is as good as mine, but in any case, it happened to be one of the more enjoyable flavors of the pack.

My overall analysis of the flavors is that while they are not spectacular, they didn’t deter me from using the device at all. I think there is enough diversity throughout the line to satisfy the more popular flavor profiles. My favorites were blueberry, mint tobacco and mint. Even though they weren’t all true to their description, they were still quite enjoyable. The tobacco flavor wasn’t my style, but it would be a perfect choice for cigarette smokers.

Battery life and charging

The 350 mAh battery generally got me through most of the day, and it took me around two charges to kill a full pod. It would have been nice if you could vape a full pod on a charge, but then that would probably make it a heftier device.

All in all, the limited battery life is not a big deal, but I would have expected a bit more, considering its size. I’m not going to call it a con, but more like a suggestion for improvement. If it ends up becoming your daily driver, you can always invest in another one down the road or just use a portable USB charging unit for emergencies.

There is an LED light on the body of the device that lights up when you vape. It lights up white, yellow and red based on the status of your battery.

White: 50-100%
Yellow: 25-49%
Red: 0-25%

It takes about 35 minutes to charge fully, which is not bad at all. You can also use it while its charging, so that’s always a useful feature to have for those times you run out of juice but can’t wait a half hour to charge it back up again.

Pros / Cons

  • Easy to use out of the box
  • Modern design
  • Provides a tight cigarette-like draw
  • No leaking spitting or gurgling
  • Realistic tobacco flavor (for smokers)
  • Decent flavors overall
  • Charges in about 35 minutes
  • USB-C passthrough charging
  • Battery life indication
  • Limited flavor profiles
  • Difficult to monitor liquid capacity
  • Slight ceramic taste


I’m seeing the kit and pods for extremely cheap right now. I’m not sure if this is just a promotional deal, but I was expecting it to cost a bit more. Without even considering price, it’s a well-built vape and is perfect for beginners. I think the X2 shows a lot of potential for OVVIO and μKERA technology. I did notice a slight hint of ceramic on a few hits, but this device excels more in performance and design than it does in flavor. It still provides more flavor than the JUUL and just as much, if not more, than pod vapes like the Mylé.

If you are just making the switch from smoking, I would easily consider this device. The only thing that would hold me back is that I’m not sure how widely available the pods will be in the future. But stock up while you can—especially on those tobacco pods, if you are looking for the closest you can get to a cigarette-style experience from a vape.

The X2 blows the JUUL out of the water in terms of vapor and flavor production. If you are looking for a simple, beginner-firendly starter kit with a solid throat hit and a true MTL-style draw, then this is it. I hope they plan to release more flavors for it someday, or even refillable pods.
