Shoot, it was suppose to run through midnight tonight. Looks like they pulled it early

I've read the entire thread and more about the safety of the silica wicks and there was a bit of professional scientific information provided. It is basically safe, considering its amorphous silica that can be processed out of the air pathways. Its also not like inhaling silica dry silica dust without protection which can lead to silicosis. While its the wild west approach to many of the ecig products, I'd like to see the same kind of discussion on the safety of the ceramic wicks they're using. Silica isn't crumbling in your hands but you have to consider that the ejuices used may effect the surface of the material used. I really liked the performance of the BVC, but after seeing two reviews showing the wicking material crumble, that seems concerning. Comments on the material were that it _felt_ like abrasives. Silica is also used in abrasives and in things like toothpaste, although eating it is different than inhaling it. I believe many cigarette filters are also silica, and they're not wetted. Perhaps that is part of the combination of factors that cause illness with smoking.
Sure, a wetted material is only "unlikely" to move particles, but what if the ceramic particles are small enough to be transported by vapor droplets? Are they amorphous or crystalline? What if the pH of the ejuice is enough to eat the surface at a microscopic level and trap them in the droplets? That's what the vapor is. I do not believe Aspires document holds any water. The've invested money and have a stake in their product. It was tested for contaminants but not physical properties. There are no tests showing the repeated real world use and material property changes over time when exposed to the heat and substances being wicked through it.
The screen is there to prevent chunks of the material from going into your mouth because it will break apart. Its not like other long strand fiber material. Silica is used in rope/string, and the intertwining of the fibers is what provides its strength. The longer, the better because it can chain to thousands of other strands and give it greater tensile strength. Cotton is also stranded fiber that is naturally made. That's why its also used to make string. It just so happens that it also makes for a wick material, and doesn't burn. I have never seen a ceramic string or rope (not to say there isnt one). Spitback is going to happen because the coil is like a tube and there is no screen covering that area. The screen is too porous to filter anything real. Also, the coil is not tightly wound and there is plenty of space between the rings to allow microscopic particles to be broken off that can pass by the coil. In searches, I ran into a few reviews of ceramic wicks being commonly used on vaporizers for ........, but I have no experience with that or know anyone that could comment.
What I didn't like about it is the feeling of the "crunchy vape" that I've seen commented on, but that might not be the material and more to do with the ejuice. I'm not sure, I can't don't have a SE microscope at home or the capabilities to use a spectrometer (or is that spectrograph or whatever I forget).
It needs to be researched and discussed. I don't want to be paranoid, but I have stopped using the BVC with this type of wick until there is some kind of more professional opinion about it.
Thanks.

I would alternate between BDC and BVC coils in my Aspire, never really had a problem.
Oh, I like the setup, but I am naturally suspicious and for good reasons. Nothing is without cost and it takes a lot of information to make an informed decision. Harm isn't going to happen overnight or a month later. This is going to come from cumulative use if it does. When they have to produce a "certification" to ensure the safety of an item like this its a red flag. Why would they need to produce this? There were obvious concerns from somewhere. Knowing the lack of protection of Asian countries concerning their own people I wouldn't rely on self regulation or certification, especially from a group that has unknown loyalties and affiliations. The track record speaks for itself. Its like saying the University of Phoenix Online is an accredited college.
I think there are too many "what ifs" about the aspire BVCs and this is going to lead to a market correction with revised materials. Somebody needs to start by producing a real standard for the wicking material. The cotton and silica used are coming from dozens of producers and there are too many variables to monitor. Playing Russian Roulette with a semi-automatic pistol doesn't work well.
I want to move to a regulated 30-50w mod with a BVC/BDC so that I can control the materials being used but figured the community might have some information to alleviate my fears of it. There are a lot of smart people out there involved in this and most of them are smarter than I will ever be

Oh and I used 3.7-4.5v on a MVP2 with mine but usually had it in auto mode on 8.0w
I use an nautilus mini with the BVC coils at 11 watts on my mvp2. I freaking love that thing. Got a few drippers and a kayfun now but still find my self going back to the nautilus mini when I need something to take with me that I know I can rely on 100%
