Hey everyone. I've used this forum as a resource for awhile but am saddened by the circumstances that led me to make my first post. About 3 weeks ago I purchased a "Stok" brand pen style vaporizer at a LHS. Here's their website: http://stokusa.com/home.htm I was about to get a Cloud but was talked out of it by the store employee who recommended I go for the Stok. He said he had one and it was much more reliable. I thought it would be the safer bet because there was plastic not too far above the heating element in the Cloud. The Stok uses a new "F5 Funnel Cloud" cartridge which is supposed to be a titanium funnel encompassing the ceramic dish and heating element. I thought the only plastic was the clear outer casing, which is quite insulated from the heating element. Before using, I tested this pen by holding the button with the cartridge still empty, watching for "mystery vapor" coming from the red hot heating element. There were no vapor or fumes visible so I thought I was good to go. Low and behold when I finally pulled off the plastic outer casing of the cartridge, I was disgusted. The wires that ran up to the heating element were coated in plastic and in areas this coating had been melting right in front of one of the air draw holes. You can see the blue stuff above that hole in the picture is melted plastic. As if this wasn't bad enough there are these mystery fibers, also visible in the pics. Not sure if this is from the wick, strands of melted plastic, or some fiberglass but either way, this should NOT be in the air path. I'm sickened to think what I've been inhaling these past weeks... Besides warning everyone, I also wanted to ask for help in terms of making the best of the situation. From what I've seen many of these pens use standard ego e cig batteries etc. I was wondering if anyone is familiar with the style of battery I have from the Stok and if there are safe cartridges I could screw on to it. I went to another LHS that carried Omicron, Ophos and Persei vapes. The cartridge from the Omicron (which is supposed to be very safe, right?) wouldn't screw onto my battery but I've heard there are adapters that could make it work? I'm very new to e-cigs/pen vapes and would be open to all recommendation on how to make the best of this precarious stituation. Ideally I want to save money and not have to be a whole new "kit" but I will if I have to. Thank you in advance for reading and for your helpful suggestions/recommendations.
