I keep reading this forum in hopes of a miracle reassurance that my stealth is safe cos I want to use it again, it is a beautiful effective piece of machinery. The reality is however, it's most likely not safe, its not all GonG and davinci does not have the resources to confirm its safety, nor do most of us without proper research lab equipment. Unfortunately, even if my ascent stops visible off gassing from an empty bowl...invisible, tasteless poisonous off gases could, and probably do, still exist. Even if DV gives us the identity of the silicone compound, the burn off may not be from the black rubber, it could be the underside of the white plastic bowl, a wire sheath like thesoloman said, or something completely else. I want to believe it'll work out, like most of you, but this desire may be blinding us to realize the sad truth that using the ascent may pose a serious health risk.
Only reassurance is that the popular flower of use, does eat cancer. (As a neurochemist i can attest its a well known scientific fact in my field). So maybe the cancer fighting properties of a filled bowl can offset the mystery poison gas run off by the ascent. Lol.
