Yosen SX Zero Modz style
The Yosen Zero Modz is based on their own SX330 chipset. The chipset is made by Guangzhou Yosen Electronic Technology Co. Ltd. – better known simply as Yosen.
In the chase for lower price and maintaining profitability, most of these companies are cutting corners. The box at the right is what I received. It's damaged and fairly cheap looking. Inside there is a form cut out area where the mod is inserted in a plastic bag. The User Manual is over that. There is also a cut out area for parts and wire, that all you get is the box, plastic bag, user manual and the mod itself.
The Yosen Zero Modz is a clone. The marketing collaterals claim it to be a 1:1 clone, but if you look up the original online, you will see a version that has an acrylic case like this, but the top and bottom covers are different. I doubt that this is really 1:1. The fit and finish of the Yosen version is so-so. I find nothing wrong whatsoever with the materials. The acrylic body is well made and no flaws whatsoever. The stainless steel is well made and also with no flaws. The threaded portions (the caps at the top and bottom) have smooth treading. The slots could be a bit wider to accommodate a larger coin. Those slots can't be any smaller, though, that would interfere with the copper pin that presses against the battery anodes. What I found with this particular unit is that the 'C' shaped stainless steel is not fully bent properly (not evenly straight). At the bends, the height is 83.5 mm – but at the extremeties it is 84.4 mm. You can also see a small gap between the stainless steel and the acrylic at the extremeties. They also could have made the edges a bit smoother or beveled slightly. The edges are not sharp enough to cut, but sharp enough to feel awkward.
The OLED on this looks similar to the screens on the new Yihi SX350 devices. It's a nice, high contrast display, that shows your wattage, battery charge remaining in a graphic representation, voltage sent to the coil with single point precision, coil resistance level (ohms), and voltage remaining in the battery in text representation with double point precision. The chipset is quite efficient and responsive. When you press the fire button, you get instant delivery of power to the coil.
This is one of the new style G-Sensor adjustable devices. If you are used to buttons, this will take a bit to get used to. It is well implemented, though. I've seen some of these sensors have very little in the way of acceleration in response. When you tilt, you are at full warp speed in adjustments. This Yosen SX 330 chipset starts slowly and accelerates through two speed levels. It just feels right as it progresses from slow to its fastest speed. It's easy if you are trying to adjust just one digit precision (unlike some of the other devices). Kudos to Yosen for getting that right!
There are two screws at the top and two at the bottom. They are 2.0mm hex head. You probably void your warranty if you open up the case – but I can't find any warranty information anyhow. The picture at the left, by the way, shows the two screws. Unfortunately it does not do justice to the adjustable 510 connector. That's a flat head screw driver adjustable copper pin (it is not floating).
The Fire button has a fixed outer ring. If you put the device on a flat edge with this facing the surface, it will not fire inadvertently. I suspect that is more for putting the device in your pocket or purse though. It is easy to press the Fire button with your thumb or finger and there is a tactile feel and sound to pressing the button.
Three clicks of the Fire button in rapid succession with toggle between lock/unlock mode. In lock mode, the system does not fire and the OLED will display a Lock icon. Three more presses in rapid succession to unlock.
Five clicks in rapid succession will get you to the main menu. Once you are in the main menu, the function you look at will have directional arrows. Lean the device in the direction of the arrow to adjust. The Left Chevron ( < ) is the same as the Minus button, and the Right Chevron ( > ) is the same as the Plus button. Click the Fire button again to cycle through the available features. There are three only: Wattage adjustment, Exit, and System. The Wattage adjustment will cycle through the full range in 0.1 watt increments. Once it reaches the minimum wattage supported (7.0) you have to go in the other direction to reach the maximum (50.0). Same when you reach the maximum, you have to go in the other direction to lower. The Exit is for you to exit the menu, just lean the device in any direction to exit the device. The System is for you to power down completely. Lean to the right or left to get the "Byebye" message and power down. To restart the system, five clicks in rapid succession.
Below the OLED display, you'll find the company logo, the micro USB port and a small hole to the left of the USB port. The small hole is for a tiny LED display that displays when charging. The micro USB port is a 500 milli-amp charger. You can vape while charging (pass-through). And, below the USB port is the device serial number.
The pictures make the Yosen Zero Modz clone look huge. It's actually quite small. Let me give you an example. It's about the same height and depth as the Vaporshark rDNA 40 ... and only a tiny bit wider. It even weighs less than the Vaporshark. And, the Vaporshark is considered one of the smallest replaceable 18650 devices available. So, don't let the pictures trick you, it's an optical illusion (and likely because of the stainless steel C shape).
So, it's small and comfortable to hold. But, it's big on delivering a very nice vape. Power transfer is DC (Direct Current). This is not a modified power stream like you find in pulse mode modulation. It's direct power transfer to the coil. That means a nice smooth vape and it delivers. It also means battery life will be a bit shortened, but it's well worth it. I used an Efest purple 2100 mAh battery and ended up with over 16 hours of vaping time. For a budget priced device, this is great.
You can see from the last picture I posted that I had a bit of fun with this device. The more I held it, the less I liked the acrylic green swirly pattern. That's just me though. So I wrapped it with some automotive carbon fiber I had around. I took the carbon fiber right to the outer edges. I like it, but again that's just a personal preference.
So, what's the verdict? Is it worth it? I like it. I like the finish, I like the weight, I like the chipset and vape experience. This is an excellent advanced personal vaporizer that supports wattage range of 7.0 to 5.0 watts. I like the implementation of the sensor for adjustment – and it's very easy to get used to. I like the USB port at the front of the device so you can stand it up on a table while charging. I like the small led to indicate charge status while it's plugged in. I like the square style OLED display. And, yes, I recommend it. Best of all, I like the price – you will too.
