I wonder how many potential customers have said that? I just don't understand some of these tank manufacturers' thought process. They're hoping to sell a finely machined and finished piece of stainless steel, aluminum, or titatium at a pretty stiff price of $60 or more. Then instead of using the preferred tank material to their pride and joy, they put a lousy piece of plastic in there.
It can't be about price. OCD at IBTanked has proven that it doesn't cost that much more to use pyrex; what, $5 for a tube? I'm shocked and disappointed at the same time that high end tank vendors have not caught on to what customers have been demanding for several months, that they want pyrex and not polycarbonate or acrylic plastic in their juice carrying devices. They don't want to be vaping on their favorite Mountain Dude juice only to find that the tube is melting their tank after spending $80 on it.
The Fluid Flask is a new, sexy-looking cartomizer tank. What's the first thing that I looked for in the spec sheet? Does it use glass or plastic? I, and apparently many others from initial comments on this tank, commented on the crazy good looks of the tank and then quickly forgot about it once we learned it used a plastic tube.
Some manufactures are starting to catch on by at least offering a pyrex or quartz glass tube as an aftermarket accessory. Hoosier Vapes (Bella and Elegance tanks), Vaporfexion (all the cartomator tanks ie Pro-V, Pro-V2, and Pro-Vex tanks), and Siam Mods tanks are now offering glass tubes as an accessory.
