[Guide] Joyetech has launched many new products since the beginning of 2015. Recently it has released a brand-new RTA, which is called ULTIMO. Joyetech defines it as a pre-made big vapor RTA with a RBA kit.

On receiving the sample of ULTIMO, the first impression it gave to me is the ordinary appearance. Neither its appearance nor the structure is impressive, and it even abandons Joyetech’s new top airflow tech and continues following the outdated bottom airflow structure.

However, after disassembling it, I’ve totally put aside my previous prejudice and begun to show my admiration towards its designer. It’s absolutely a creative product! 

Then what are the secrets of ULTIMO and what makes it special? In this passage I’ll lead you to discover them.

ULTIMO is packaged inside a paper box whose coloring follows Joyetech’s tradition. The front face is imprinted with the pattern of ULTIMO, below which listed the highlight parts of it—the ceramic pre-made coil head and the creative RBA kit.

ULTIMO adopts the newly released 0.25ohm MG QCS and the 0.5hm MG Ceramic. 

On the back are the brief description and the standard configuration of the product.

The inside of the box is also clean and simple. The atomizer lies in the right center, below which is the accessories package.

Besides, there is also a handbook, an attention card and a bag of cotton in the box.

The accessories package contains two coil heads, a stainless steel drip tip, several sealing rings, and a standby glass tank.

Seen from the appearance, ULTIMO is a big vapor atomizer.

After disassembling it, we could see that ULTIMO has six parts: the drip tip, the top cover, the tube and evaporation tank, the glass tank, the coil head and the base. Its overall structure is simple with fewer parts, being convenient to disassemble. 

We could see through the picture that the coil head and base are apparently distinct from those of the existed atomizers.

ULTIMO’s drip tip is double-deck. The steel inner tip is directly covered by the black drip tip and fixed with three sealing rings. This design could effectively avoid burning the mouth.

The top cover that plays the role of sealing the tank and insulating heat is also simple.

The tube part integrates the liquid filling components and the evaporation tank, and is responsible for fixing the glass tank and connecting the top cap, the drip tip, the coil head and the base. The appearance of the evaporating tank is similar to that of SQR, which could help to adjust the flavor. The diameter of the tub is relatively big, which could ensure the effectiveness of vapor exhausting. Therefore, ULTIMO should be a RTA that combines big vapor and good flavor.

 

Another feature of the evaporation tank is that it only covers the upper half part of the coil head, and the liquid flow holes are exposed to the air.

The base structure of ULTIMO is special. Atomizers’ positive electrodes often adopt the form of mandrils or screws, with one side connecting to the bottom of the coil head, while ULTIMO has an extra special accessory connected to the positive electrode to adapt to it.

The MG coil head’s electrode diameter is large, and the hollow part of the center is the air flow port that directly connects the coils’ center, which is isolated through the insulation materials and the coil head’s shell. This kind of electrode structure often need assorted positive electrodes, therefore the base is equipped with an extra hardware that could not only connect to the coil head’s positive electrode but also lead the airflow into the coil head.


ULTIMO is equipped with three MG coil heads. Besides the pre-installed 0.5Ω Clapton coil head, there is also a 0.5Ω ceramic coil head and a 0.25Ω QCS.

The structure features of this series are big diameter, large size and short height.

The biggest highlight is the 0.25Ω QCS RBA, which has the same basic structure with other pre-made coil heads except for the relatively higher height. There is a small rising section with several holes in the center, then what is it for and where is the electrode units?

Unscrew the upper parts of the coil head and you will find that QCS adopts the NotchCoil stainless steel coil, which is wrapped with a layer of cotton. 

Use a tweezers to clamp the coil and pull it outward, then you could fetch the coil out.

After the coil is fetched out, we could see that besides the four liquid supply holes, there are also several airflow holes on both the sides and the top of the rising part. Different from the traditional RBA bases, it has no electrode mandril and screws.

There is no leading wire on the stainless steel coil at all. Just clean the coil and change the cotton each time you want to rebuild it, sparing the trouble of turning the screws. The bottom of the coil is connected to the positive electrode inside the coil head, and the top is connected to the coil head’s ektexine through the fixing ring, making up the current circuit..

The cotton send by Joyetech is strong and tight, therefore is convenient for operating. However, these original cotton will be used out in the end, therefore I’ll take MUJI’s cotton instead to conduct the test in this passage. 


Cut a length of cotton according to the size of the original ones. Because MUJI’s cotton is a little bit fluffy, therefore we’d better impact it before comparing it with the original cotton and deciding the size.

Wrap the coil tightly with the cotton, and to better finalize the cotton’s shape, we could soak the cotton while wrapping. 


Be carefully not to cover the edges of the coil with the cotton, otherwise it will fail to carry the current. If the cotton is too wide, cut the excessive part with a scissor.

Put the coil inside the coil head after finishing. At this time the coil head hasn’t been connected to the negative electrode and forms the circuit yet. 

Soak the cotton thoroughly and drop moderate liquid into the four liquid flow holes on the bottom too.

Screw tightly the top fixing ring and the rebuilding is finished. The process is so easy even for newcomers. 

The fixing ring is pressed on the top of the coil and is connected to the coil head’s ektexine through the threads, which means that the negative electrode is also connected. Then install the coil head on the base and power on to burn the cotton for the purpose of odor removing.


The air path of QCS is also special. It adopts the erect structure, where besides the holes on the bottom, there is a small air hole on the top too. We could judge from the structure that the size and position of the holes are carefully calculated and improved.

As mentioned above, ULTIMO’s evaporation tank only covers the upper half part of the coil head and the liquid flow holes are exposed outside the tank, therefore the liquid circuit could not be closed. Before filling the liquid, close the bottom air flow holes first to prevent the liquid from penetrating.

Actual Experience:

A. Flavor

Among the three coil heads that ULTIMO provides, I personally think MG Ceramic 0.5Ω is superior to the other two in flavor. The ceramic liquid flow technology could produce accurate, clean and smart flavor, moreover, it ensures high reduction of the liquid.

The following is the pre-installed MG Clapton 0.5Ω and QCS. They both are distinctive in flavor. For QCS, its flavor under the 316 temp control mode is not as rich as when under the voltage adjusting mode.


No matter matched with which coil head, ULTIMO always performs well in flavor. In comparison, its vapor performance should be counted as only an additive attribute. 


B. Vapor Volume

ULTIMO is a big vapor RTA. The vapor volume of the three coil heads are all above the average, especially MG Ceramic 0.5Ω, who boasts both pure flavor and substantial vapor. But different from voltage adjusting coils, the ceramic coil heads need bigger power to show their characteristics. For example, common coils' voltage are between 3.2 to 4.5V, while for the ceramic coil heads, the voltage should be at around 5V to achieve the best flavor and vapor volume.

Both the Clapton and QCS coil heads could perform well in vapor volume while keeping good flavor at the same time. 


C. Ease of Use and Reliability

The two pre-made coil heads carried by ULTIMO both do not have the trouble of liquid leaking or splattering, thus having high reliability. QCS is extremely simple that we only need to fetch out the coil and change the cotton to rebuild. If the surface of the stainless steel is generated with carbon disposition after long-term use, just clean it with water, or it will better to apply an ultrasonic cleaner. 

As for the liquid consumption, ULTIMO, being a big vapor RTA, inevitably has relatively high liquid consumption. Under the same data, ULTIMO’s actual consumption is similar to that of like products. The longer you use it continuously, the larger the consumption will be. 


D. Disadvantages

ULTIMO’s QCS coil head adopts the big diameter NotchCoil coil, whose properties include large heating area and fast heating speed, therefore will lead to high temperature of the atomizer after continuous use.

While using QCS, there is another problem concerned with the condensate fluid. The boiling liquid from the cotton caused by NotchCoil’s fast and large heating will spread among the center holes and the top of the evaporation tank. Though they will neither enter the air path and be inhaled along with the vapor nor produce apparent splattering sound, the condensate fluid accumulated on the tank’s top will flow out from the drip tip when the atomizer is put upside down. Therefore, during our everyday use, we could toss out the fluid by lightly shaking the atomizer for several times to prevent them from flowing out. 


Another disadvantage is the shape and position of the coil head’s liquid flow holes, which will lead to residual liquid on the bottom part of the tank. For that reason, each time we are going to replace different kinds of liquid, we have to disassemble the device and clean it first. Moreover, this will lead to unnecessary waste.

Summary: ULTIMO is a special atomizer. It is not distinctive at all in the appearance, but the coil heads’ structures are innovative. It performs well in both the vapor volume and the flavor. Though there are some problems yet to be improved, the atomizer is overall a practical RTA that boasts big vapor and good flavor. It provides the easiest way to rebuild the coil head and recover the original flavor and performance. 


I personally think ULTIMO is a new try for Joyetech. Since the innovation of the top airflow structure at the beginning of this year, Joyetech has been releasing several series of products revolving around its new techs. Therefore, I think more products that apply the MG structure will come out and face the market sooner or later.
