If someone here has a colonoscopy I will take their word for it, I don't need to see pics.

This is silly. I vape and still am able to focus on my goals/career & family.

Hey guys, So the other day I got this email from Uwell about Ceramic coils. What do you guys think? The Truth and Science behind Ceramic Coils Customers have asked why Uwell doesn’t makes ceramic coils since the ceramic coil has a longer life compared with the Crown 2 coil and some ceramic coils even have better taste. The article followed contains some researches and analysis of how ceramic coils affect vapers’ health and it may help to answer the question. Uwell realizes the short life of the Crown 2 coil and we are developing coils to taste better and last longer. The latest version has increased life time and is now on the market. The good news is that there is positive response. Figure 1 shows three kinds of ceramic coils on the market (#1, #2, and #3 stands for three different brands, respectively). For #1, there is a layer of cotton between the ceramic and the coil. This design is lower in strength and makes the ceramic fragile. For example, the ceramic coil breaks apart when pinched and tiny powders fall off and stick onto the cotton. It is also hard to distinguish the cotton and the ceramic material since they are both white. In the case of #2 and #3, the ceramic material and the coil are heated up together to be made into one piece. However, the melting point of the coil is lower than the ceramic material so this causes the surface of the coil to be loose and porous. This makes the coil have low durability, is fragile, and has powders falling off. Figure 2 shows partial end surface microstructure of #1, #2, and #3. All three ceramic coils appear translucent with a glasslike exterior. Visible light can be reflected and scattered by pores inside the ceramic material. This is what makes it a translucent surface. The ceramic coil is made from silica similar to glass. Therefore, the ceramic coil appears as a glasslike surface. Many impurities can be seen at a magnification of 100X from a microscope and they appear as black spots. The glasslike particles are not uniform and appear to be uneven and chaotic. The tiny glass pieces have sharp surfaces that can scratch the trachea and alveoli when used. The black spots could also be unrefined toxic material that could have impurities. Figure 3 shows partial cross section surface microstructure of #1, #2 and #3. After breaking the material for the cross section, we can see glasslike particles with sharp surfaces. The glasslike particles are clearly visible at the magnification of 100X. Figure 4 shows partial edge surface microstructure of #1, #2, and #3. Some parts have defects and some parts have sharp edges. This comes from two steps in making the ceramic coil. In the first step, the friction causes defects and coarse edges when samples are removed from the mold. In the second step, the surface of the ceramic coil is loose from the friction between the ceramic powders and the mold. The loose powders cannot be heated up and molded onto a dense body. The ceramic powders also stick to the surface of the ceramic coil. This process also makes the ceramic powders fall off easily. Figure 5 shows ceramic powders falling off microstructure #1, #2, and #3. When the ceramic powder is touched, the powder sticks onto that surface. All these powders are glasslike pieces with sharp edges mentioned above in the optical microscope. The size of the ceramic powder is distributed between 30120 micrometers which is too tiny to be seen by the human eye. Figure 6 shows the microscope image on the contact segment between ceramic and coil. Number #1 does not compare with others since its coil does not come in contact with the ceramic material. Many ceramic powders gather at the position near coil. The first reason is that the coil cannot be easily compressed into a ceramic material when the ceramic material is molded. This is because the cross section of the coil is circular. The second reason is that powders are produced after taking the coil off of the mold. It is impossible to clean the powders stuck to the inner surface of the ceramic coil. There are ceramic powders on the inside of all ceramic coils on the market. Finally, ceramic coils may cause death. Making the ceramic material The ceramic coil is made from inorganic porous ceramic material. There are tiny pores inside the ceramic material that cannot be seen. Pores play an important role in wicking. In order to produce a porous ceramic material, raw materials such as silica powders and poreforming materials like starch or other organic polymers are needed. Then they are mixed and put into a mold with high pressure. Samples are obtained with a fixed shape. The samples are put into a furnace and set to a high temperature. Pores are formed while the poreforming agent combusts and escapes. This kind of pore plays an important role by introducing eliquid into your vape. However, to make enough pores, the temperature to stick the materials together is lower which causes low tensile and compressive strength. The powders fall off or crack when the ceramic coil is touched or shaken. All the powders can be introduced into the lung by air which is dangerous (the speed of air can reach 223mph when we are vaping). Vaping Ceramic coils will absorb more eliquid. Eliquid is vaporized and evaporated when the coil is working. High pressure from the vapor will expand and damage the structure of the porous ceramic material. Loose powders will fall off and go into the lung. Causing death Silicosis is a form of occupational lung disease caused by inhalation of crystalline silica dust. Symptoms are inflammation and scarring in the form of nodular lesions in the upper lobes of the lungs. This is a type of pneumoconiosis. Silicosis can be complicated by the development of severe scarring, where small nodules gradually merge together, reaching a size of 1cm or greater. Progressive massive fibrosis is associated with more severe symptoms and respiratory impairment. Silicosis can also be complicated by other lung diseases such tuberculosis, nontuberculous mycobacterial infection, and fungal infection, certain autoimmune diseases, and lung cancer ("Silicosis." Wikipedia. Wikimedia Foundation, n.d. Web. 29 Sept. 2016.)(https://en.wikipedia.org/wiki/Silicosis). In conclusion, ceramic coils are not healthy. First, a ceramic coil is made from silica similar to glass. Second, ceramic powders or glasslike pieces easily fall off. Finally, silica powders may cause death. Uwell is working hard to develop a better ceramic coil. However, it is impossible to continue with current technology. Therefore, Uwell will put making a ceramic coil on hold. Uwell wants to tell customers the truth. Uwell will never produce a product that causes death. Would you buy a coil that lasts longer at the cost of your life?

Got it! Took it apart. Spring went flying but quickly recovered. We are up and running. Thanks very much! Sent from my iPhone using Tapatalk

Don't know what you mean by flavor going backwards, but most people say the higher the PG the more flavor. The amount of flavor depends on the flavor used, in the case of coffee I only use 6%, other flavors I use as much as 25%. I try to stay about 20% flavor, but sometimes you will need a little more sometimes a little less. It all depends on what you like. I don't believe there is a set amount especially when using multiple flavors in a mix.

Here is a link to rebuilding a Subtank mini RBA, it is a older style RBA, but the basics are the same. rebuilding is not for everybody, but it does save a lot of money. http://allaboute-cigarettes.proboards.com/thread/50745/kanger-subtank-mini-build-guide

I did a little checking, and the nearest cell tower is about 12 mi from me, and there is a couple of buttes between there and here. There has been talk of getting a cell tower out here, but that's all its been is talk. The tower I get my internet from is only about 1/2 mile away. I thought about using the net connection for a phone, but haven't done that yet. Sounds strange but I get 7mbps internet service but no cell phone service.

For some people like me it is not easy to post a pic, I don't have a smart phone because they don't work where I live. Our digital camera works great for vacation pics and stuff like that, but doesn't do well on close up pics, And I can't see posting a fuzzy pic. It is actually easier for me to post a rendered 3D cad drawing than a pic. Usually when I do post a pic I find something on the net, and do a copy and paste. The avatar I use was taken with a digital camera which I had to upload to my computer from the camera so I could use it. Just saying some of us don't post pics because its a PITA.

Spin-off or knock-off. It does indeed look like a combination of the RX200/Reauleaux DNA200 and the RX2/3. Almost the exact same dimensions of an RX2/3 in dual 18650 configuration with the same large +/- button, but with the smaller screen of the RX200/DNA200.

Re-Buildable Atomizer In this case, it's a deck (bottom part) that goes on your tank that allows you to build your own coils for it.

The Subox mini uses a 18650 battery, I hope you ordered one for it, I use the LG HG2 battery in my Subox mini mods, but there are other batteries available that will work just as good.

The Subvod mega to the best of my knowledge uses the same tank as the Subox mini. They both use the Toptank mini, so the coils you currently use will work. The biggest difference is the Subox mini kit should come with a RBA. I currently use 2 Subox mini 75w mods, and never get close to using 75w. The most watts I have used with that tank was about 35w and that was with a .5 Clapton coil.

Thanks and for the record the simple fact that you asked for pics I would of never posted them

Thank you everyone. I actually ordered a Subox mini yesterday so I am hoping that will be better. I know it's probably not the best upgrade I could get but it's what I have the money for until I can purchase the alien kit. Sent from my 9020A using The Vapor Talk mobile app

Take my word for it I have Rx's lol

Google search turned up several vendors with this mod $38-$44 ..to me it looks like a spin-off of the RX200... Sent from my XT1585 using Tapatalk

Interesting read, Thank you for posting this.
