Reviewer comments on business characteristics

Yihi, the famous high-end Chinese designer, offers his latest creation. For those who do not know, Yihi has made a name for itself with its chipsets that compete clearly with those of the American Evolv, both qualitatively and in terms of innovation. Then, this Chinese brand has decided to offer itself beautiful "cases" for its renowned electronics through box well designed and well designed.

Much like a major car brand, Yihi continues to propose changes to its standards, but at a decent pace, which often allows them to produce products that are successful and flawless.

Today, it is the most compact of its creations, the SX Mini, which sees its line lengthen by a new version: the MX Class. Based on a simple 18650 battery, like its predecessor the ML Class, it takes the "spirit" style in part. It is equipped with several new features: color screen, "joystick" button and Bluetooth connection. All, managed by their latest chipset: the SX480J-BT.

A box whose rate confirms that it is part of the top of the basket. 159 € is a sum, but when you want the best, you have to know how to put the price.

So, let's see if the latest flagship of giant Yihi is still up to the expectations of high end fans.

Reviewer's comments on physical characteristics and perceived quality

On the physical level, I would simply start with: Wow !!! She's pretty, this new SX Mini MX class. The previous version, the ML class, was already very successful and it was not easy to do better while maintaining the lineage of this lineage.

Yihi's designers propose us an evolution coherent with the inheritance of the preceding generations while offering a personality peculiar to this MX class.

I can not objectively tell you why I have this analogy in mind but, for me, it finds its basic inspiration from the German manufacturer Mercedes. I would even say that the physical evolution of the models seems to follow that of these cars.

One of the style effects of this new model is at its base where we discover a recessed space. As on some car models, we find this type of detail that exists to provide a kind of aesthetic signature, while providing aerodynamic improvement and weight gain.


This new SX Mini offers a drawing that is both sober, refined and racy. The harmonious combination of curved, soft lines and more taut and dynamic lines gives a perfect result. Indeed, our compact is a striking beauty.

We begin with our fire oval button that follows the curvature of the surface on which it arises. As always, this button is absolutely perfect.

Below, the TFT ips HD color screen and a single interface button of half-spherical shape which makes it is a kind of Joystick complete the endowment. Then, finally, the micro USB port sits at the base of the facade.


On the top of our box, there is an 510 connection cut into a disc of 24mm steel. The devil hides in the details and, if we look at this piece, we realize that the edge of the disc is slightly concave.


The back of the box accommodates the hood of the cradle that receives the battery. This piece is a little more "massive" than the rest, a small detail that seems to have originated from a desire to offer better ergonomics. We note well on the cartridge with the round edges of steel color engraved in the name of the box.

The compartment that receives our 18650 is of course perfect and the cover that covers it is adjusted to the millimeter, no game, not the smallest gap.


A new opus perfect, both in terms of very successful design as the quality of manufacture.

The new SX Mini is beautiful, well inspired and very qualitative, in short, it is perfect. It is, in my opinion, one of the most beautiful 18650 simple box of his generation.

Reviewer's comments on functional features

Do I really need to announce that our MX class has everything you need in terms of technology and function?

Indeed, the new chipset SX480J-BT knows how to do everything: bypass, variable power, temperature control, TCR and Joule mode (a mode specific to SX which is similar to a TC mode but which measures the heating compared to a heat meter). It gives you access to all current modes of vape.

In variable power mode, the beautiful can take you to 75W, in TC mode the temperature can reach 300 ° C.

TC functions are compatible with titanium, Ni200 and SS coils.

The value of the accepted resistance will be the same regardless of the chosen mode, it must be between 0.05 and 3Ω.


There is also a booster with five predefined puff profiles (Eco, Soft, Standard, Powerful and Powerful +), but you can also create your own profiles using the manufacturer's software.

Always in the idea of ​​customizing your box, you can also choose the components displayed by the TFT screen.

The color HD TFT ips screen displays by default: the power or temperature or the joules according to the mode chosen. There is also a counter in joules, the value of the resistance, the voltage, the intensity in ampere, the chosen boost, the charge of the battery.

The micro USB port will be used to connect your box to your PC and thus configure everything with the software, while serving as a backup charger.

The box is equipped with a Bluetooth connection that allows it to be connected to a smartphone, it will be discussed below this function.

The electronics offered by Yihi are visibly top, complete and accurate, this new SX has everything you need to honor its ancestors.

Reviewer's comments on conditioning

Here too, the Chinese brand has been able to appropriate all the codes of the high-end: a white box type "pavé", wrapped in a transparent plastic sleeve type frosted. On the lid, we find the brand that fits in all simplicity in a brilliant black. On the back, the contents and the legal notices.

Inside, we find our box, a USB cable of good quality and the notice that includes a part in French. There is also a kind of transparent film pellet rather rigid, intended to be glued on the base of the box in order to preserve any scratches.


The box is, itself, contained in a small paper bag with the colors of the brand. There is another small white box that contains the protective skin of the box.

A presentation, simple, sober and class that fits perfectly in the spirit of the box.

Reviewer's comments on the use of the product

First point, the box is compact so easily transportable. Similarly, the silicone skin will protect it well, despite the fact that it spoils a little visual appearance of the beautiful.

In terms of ergonomics, here too the SX mini is one of the good students. The design in addition to being to fall offers a very good grip.

The battery change is childish, no particular difficulty, the compartment is accessible at will. Except when the skin is in place, it goes without saying.


In terms of ergonomics, there is the base of five clicks to start, but the rest is to learn. Indeed, it is necessary to appropriate the new system of joystick, I do not make you a detailed description, I will just say that each movement of the latter opens the different settings and that this system requires a little time of adaptation but that it remains accessible.

Our box is equipped with a Bluetooth connection, so it can be controlled through a free application, available on Android and Apple Store. In this case, the setting of La SX mini is made in all simplicity especially that the connection is done well and that every action on your mobile will be transmitted immediately to the Box.

The application is very well done, it can fix everything without any harm, it is very similar to the micro version except that we can not change or customize the display that is reserved for the PC version.

There is no need to tell you that the vape offered by this beautiful box is part of what is best in the genre. The SX mini chipset are as efficient as those of Evolv for example.

Not much to say more, the new SX Mini is really nice to live.

The mood ticket of the reviewer

It is difficult to find a conclusion to a test that we would almost never finish as we fall in love with this box.

First of all, she is beautiful, her drawing is just perfect. The curvaceous and soft lines are associated with more straightened lines in an irreproachable harmony. A style effect particularly well felt at the "foot" of the box comes to complete this design already very successful. The finishes are irreproachable, like what the Chinese, when they want, they can.

Metal controls, always as efficient and well adjusted, reinforce the qualitative sensation that emerges from our MX class.

A TFT screen of very good quality accompanies a new chipset that inherits the intrinsic qualities of its elders. An impressive number of settings give you great possibilities to customize your vape and the visual features of the display. Something that can be tricky with the physical controls of the beautiful but, thanks to a Bluetooth connection of very good quality, becomes a breeze.

So what can be blamed for such an achievement? Some will tell me its price!

We can indeed find that our pretty Chinese is overcharged. But in fact it is not, we have a high-end product that has nothing to envy to European High End productions, both qualitatively than on the engineering or even design.

I have no choice but to salute this new opus of the SX mini by awarding a TOP MOD rewarding a product almost perfect.

Good Vape
