Reviewer comments on business characteristics
Revised copy by Ehpro for this 2 version of the Billow, with much larger air flows, wider channels, a double bell and an 6mm internal diameter chimney. These are the main changes for the ultimate, make this Billow V2 a beautiful special steam engine for the sub-ohm and vape well beyond the 30watts.
It is a small atomizer in the look of sub-ohm clearomizers that allows us a substantial reserve of liquid 5ml for a price quite correct.
Great improvements that allowed me to vape at more than 40 watts with a resistance a little higher than 0.5ohm to provide dense vapor clouds and barely warm. But let's take a closer look at this.

Reviewer's comments on physical characteristics and perceived quality
The look of the V2 bilow has been improved, as has its performance.
A drip tip is shorter, the top cap has become thinner, for the body of the atomizer we keep a similar tank but the biggest change comes from the very wide chimney, a double bell and the base.
The base is no longer equipped with two all on each side, but rather two cyclopes that can be adjusted via a swivel ring. A very simple and especially practical manipulation. Its size was also revised to 50mm (instead of 54mm).
The diameter is common with its 22mm and the capacity of 5ml is huge.
Super machining on a stainless steel that does not especially mark fingerprints. The joints are of good quality and I had no problem with the threads that perfectly assemble the parts.

Reviewer's comments on functional features
It is a small atomizer with a sub-ohm clearomizer look that makes it possible to make large, very dense clouds.
The tray remains sufficient and everything is functional, but its size restricts the diameter of the coils to 3mm. To make a size above would be risky.
There is not much room for this Billow V2 which is practical with a nice capacity of 5ml of liquid.
The air flow is easily adjustable with its swivel ring and the pin is adjusted with a screwdriver.
Simple and effective functions. The only special feature is the double bell that serves to confine the steam for better flavors and dissipates the heat very well by distributing it.
Drip-Tip Features
- Drip tip type: 510 Only
- Presence of a Drip-Tip? Yes, the vaper can immediately use the product
- Length and type of drip-tip present: Short
- Quality of the present drip-tip: Good
Reviewer's comments on the Drip-Tip
A simple Drip tip in stainless steel of small size, since it measures only 13mm, with a base 510 in PMMA.
Its internal diameter is important. On the side of its connection it measures 6.5mm and makes 9mm on the mouth side.
Pleasant and sôr, it finishes well the look of this atomizer.
Evaluation of the packaging
- Presence of a box accompanying the product: Yes
- Would you say that the packaging is up to the price of the product? Yes

- Does the manual explain ALL features? Yes
Vapelier's note on packaging: 4 / 5 
Reviewer's comments on conditioning
Although the manual is in English, all the features of this atomizer are perfectly understandable by the large number of photos that is included.
In a rigid cardboard box all the necessary is provided up to the pad (Fiber Freaks Original) and the pre-assembled resistances. That said, I still doubt that you can install these resistors of a diameter of 4mm which seem to me oversized compared to the useful diameter of the plate.
The intention was there, but Ehpro overestimated the capacity of acceptance of the diameter of the heating chamber with these resistances provided, in my opinion the risk of CC is very important.
Appreciations in use
- Transport facilities with mod of test configuration: Ok for an inner jacket pocket (no deformation)
- Disassembly and cleaning facilities: Easy but requires a workspace
- Filling facilities: Easy, even standing in the street
- Easy to change resistors: Easy but requires a workspace to lose nothing
- Is it possible to use this product throughout the day with several vials of EJuice? Yes perfectly
- Was there leak after one day of use? No
- In the event of leaks during tests, descriptions of the situations in which they occur
Vapelier's note on ease of use: 4 / 5
Reviewer's comments on the use of the product
The plate is made to make double coils, it remains however restricted by a ring that screws around the assembly, leaving little space. The assemblies are easy to do thanks to the 4 independent screws, but the diameter of the coil must not exceed 3mm without taking the risk of short-circuiting the resistance on the edges with the ring. Despite everything, this atomizer is made for sub-ohm with large openings under the resistors for the passage of air, which are perfectly effective.
The channels have been judiciously adjusted with two drops. More flared on the top of the tray, they allow to insert the tip of the wick without crushing it.
On the basis of the two air flows are cyclope type and can be adjusted by a swivel ring. A practical and paying system, since they have a size of 2mm x 7mm with a powerful heat dissipation.
The pin is a copper screw that fits very easily with a small screwdriver. For filling the tank, the end cap of a plastic bottle is more than enough.
The novelty also comes from a room that includes, bell and fireplace. It is screwed above the ring that already acts as a heating chamber, allowing the crawlspace between the 2 metal parts to provide even more efficient heat dissipation. In addition, the internal diameter of the chimney being 6mm, as you can say that this Billow V2 allows beautiful aspirations for a thick and consistent vapor

The mood ticket of the reviewer
This little Billow V2 has been improved a lot: A sub-ohm Clearo look, huge capacity and great performance.
This atomizer is mostly made to sub-ohm, with powers around 30 and 50 watts. In Kanthal, its steam remains warm because everything is done to dissipate the heat as much as possible: The combination of the containment ring with the bell has a double interest. That of distributing the heat at best, but also to have more concentrated flavors. The air flow has also been enlarged to allow dense steam production. The channels are adjusted so that the capillarity is best done without clogging or "dry hit" effect. Up to the drip tip which is equipped with an 510 connection in PMMA.
The result is fabulous with the return of beautiful flavors and especially dense vapors and a perfect hit.
