Reviewer's comments on physical characteristics and perceived quality

It would be very difficult not to appreciate such a masterpiece. Always dressed in a black pane with a slightly granite touch like the Duke Meca previously released, this Duke Sx350J2 is made of anodised aluminum. Its top cap, its switch as well as its facade consisting of the screen and adjustment buttons are them, aluminum with a brushed finish.


The 510 connection is made of stainless steel with a spring-loaded pin. Under the box, the introduction of the accumulator is done by unscrewing a small round bonnet, which is in two parts and contains two degassing holes. The central copper part is based on the negative pole of the battery and can be adjusted according to the format of your battery (the range is minimal).




The other side of the Duke is a little bulging, allowing to have a more comfortable grip of the box. On the bottom of this face, in steel color, the serial number and its name: "DUKE".


The two broad sides are identical and inlaid with an elegant relief along the length. One of the two sides is adorned with an aluminum escutcheon, bearing the superb logo of Vicious Ant. A badge of good size that fits well in the look, almost aristocratic, this box.


The top course is not completely flat. In profile and at first sight, its appearance seems inclined linearly but in reality this inclination is in two stages. On the first 21 millimeters, the switch is inlaid on a real inclination. Then, the 510 pad is based on a flat 25mm, surrounded by a riser that continues the rising effect and borders the atomizer 22mm or 23mm when screwed on the connection. A beautiful optical illusion continues by the aspect totally inclined at all but, I assure you, the atomizer rests flat on the box!


The OLED 0.91 screen is rather wide and contains a lot of perfectly readable information.

The contact buttons, like the switch, are very responsive and perfectly integrated into the chassis.

Overall, the box has a somewhat unusual size due to its nice line away from rectangular profiles. It is rigorously constructed of T7 type aluminum alloy which gives it an excellent resistance to corrosion. Its measurements are 26mm of depth on 46mm of width and 77 with 87mm in the height, with this inclination of one centimeter.

Needless to say, and yet I do, that all elements of the Duke Sx350J2 are certainly well assembled.

Reviewer's comments on functional features

The functional features are not lacking on this Duke SX350J V2.

To begin, rather than flooding you with a text buzzing on the technical aspects, I prefer to present the table specific features of this box (in fact, its chipset), provided by the engine designer Yihiecigar


- Variable power from 0 to 75 Watts.
- Resistances accepted from 0.15Ω to 1.5Ω in variable power mode and from 0.05Ω to 0.3Ω in temperature control mode.
- The temperature range is 200 ° F to 580 ° F or 100 ° C to 300 ° C.
- The choice between 5 vape modes: Power +, Powerful, Standard, Economy, Soft.
- Ability to save in 5 memory different types of operation.
- The temperature control mode can be applied on Nickel, Titanium and SS304.
- Possibility of manually setting the initial resistance for the temperature coefficient (TRC config resistance)
- Ability to manually adjust the temperature coefficient or let the chipset use the probe to adjust the ambient temperature by probe (Gravity Sensor System)
- The orientation of the screen can rotate to the right, the left or it can be done automatically by manually switching the box.
- The By-pass function makes it possible to use the Duke as a mechanical box by inhibiting the electronics. So, the capacity of your Duke can go up to 85W power.
- Recharging by micro USB port
- The chipset has an anti-dry-brown technology and it can be updated on the site of Yihi.

This box also has other properties like the OLED screen 0.91 'adorned with the Vicious Ant logo and many security features such as:

- The inversion of the polarity.
- Protection against short circuits.
- Protections against resistance too low or too high.
- Protection against deep discharges.
- Protection against overheating.

And many more, I must certainly forget, but I admit that without notice it is difficult to list everything without omitting anything ...

Reviewer's comments on conditioning

For a luxury product, I regret the weakness of the packaging. Although the box is pretty with a lizard skin exterior decorated with the logo of Vicious Ant embossed and a cozy interior that surrounds the box. Enjoy it because that's all you'll have.

I would have liked to find a USB cable for reloading or upgrading the firmware and a manual for this chipset which is extremely provided in possibilities, manipulations and many other things that require a manual worthy of the status of this work . This is unfortunately disappointing, especially for the price!


Appreciations in use

  • Easy transportation with the test atomizer: Ok for an inside jacket pocket (no deformations)
  • Disassembly and cleaning facilities: Super simple, even blind in the dark!
  • Easy to change the batteries: Easy but requires a workspace to lose nothing
  • Did the mod heat up? No
  • Has there been erratic behavior after one day of use? No
  • Description of situations in which the product has experienced erratic behavior

Vapelier's note in terms of usability: 4.5 / 5 4.5 5 out of stars

Reviewer's comments on the use of the product

Its use can be simple or a little more complex depending on the mode chosen.

At first, ergonomics and handling are pleasant and comfortable. A correct size, a non-slip coating and very responsive buttons. Although the use of the switch on the top-cap is not usual, it is done very quickly. However the reliability of the switch was a little sad because, during the use of the box (over more than a week) and twice, the button remained depressed. By re-pressing, this is easily resolved but is it a design flaw, a defect inherent in the test model or is it a run of juice that could have pasted the switch at that time? I looked on the canvas and obviously no one has made this observation, so be careful not to run the liquid because cleaning may be dangerous.

For the operating mode, in order to access the various settings, there is also total black. Difficult to find a semblance of explanation unless you are bilingual and venture out hours on sometimes random videos of some users.

So, I start the procedure for use of this "super" chipset, to make your work easier:

- 5 clicks (on the switch) to turn on / off the box.
- 3 clicks to lock / unlock the adjustment buttons.
- 4 clicks to access the menu

Two proposals are made: "AVANCED" or "NOVICE"
With the [+] and [-] adjustment buttons, you choose and switch to confirm:

1. In the configuration NOVICE Things are simple. By pressing the switch, you scroll through the choices in this configuration:

- EXIT: on or off (you leave the menu)
- SYSTEM: on or off (you turn off the box)

In this Novice work mode, you vape in the variable power mode and the setting buttons are used to raise or lower the power value.

2. In the configuration avanced Is a little more delicate. You confirm this configuration by pressing the switch and several choices will be proposed to you

- 1 CONFIGURE: 5 possible storage options. Enter one of the 5 by scrolling through the choices with the setting buttons and select with the switch.
- ADJUST: choose the power of vape to record with buttons [+] and [-] then switch to validate
- EXIT: to exit the menu with on or off
- BYPASS: the box works as a mechanical mod, validate with on or off then switch.
- SYSTEM: turn off the box with on or off
- LINK: on or off then switch
- DISPLAY: direction of rotation of the screen left, right or auto (changes direction by manually switching the box)
- POWER & JOULE: on the mode POWER

o SENSOR: on or off

- On the mode JOULE for temperature control:

o SENSOR: on or off
o 1 CONFIGURE: 5 choice of memorization possible, enter into one of the 5 by scrolling through the choices with the adjustment buttons and select by the switch
o ADJUST: choose the value of the joules for the vape to record with the [+] and [-] buttons then switch to validate
o ADJUST: adjust with the [+] and the [-] the desired temperature
o TEMPERATURE Unit: choose between display in ° C or ° F
o COIL SELECT: Choose between NI200, Ti01, SS304, SX PURE (choice of CTR setting value), MANUAL TRC (choice of CTR setting value)

Attached is a temperature coefficient table of the resistive wire for 1Ω / mm with 28gauges and the value of the recommended resistance.


When you exit the menu, in AVANCED mode:

Just press [-] to scroll through your vape style: Standard, eco, soft, powerfull, powerfull +, Sxi-Q (S1 to S5 previously memorized).

When you press the [+], you scroll through the modes that you have put on each M1 memory to M5

When you press [+] and [-], you access the quick setting of the initial resistance and then go to COMPENSATE TEMP.

I think I went around the settings with the essential for its use. However, although the USB cable is not provided, know that you have the opportunity to update the software and set up your box via the PC and access other utilities such as defining your profile. I let you discover all the performance of this Duke SX350J2.

The mood ticket of the reviewer

This Duke SX350J2 is a real success, a little jewel with an excellent chipset: the SX350 J second version of YiHi.

As usual, Vicious Ant presents an exceptional product, in an original format, decorated with a badge that brings nobility to a prestigious and excellent quality.

Admittedly, the price is a bit spicy, which is why I am very disappointed by its packaging that provides no USB cable or record.

These features are endless quasas and its mode of operation can adapt to both novices and pros. I have spent a good deal of time trying to give you the procedure for its use to save time, it also allows you to have an overview of the capabilities of this wonder.

Good vape
