Of course, I can't be 100% sore, but the tank sections or even
this one are PEI. The top fill tanks might be very well coloured something else. I avoid to test them with cracker juices, however.
Well, FT isn't the one who should investigate about materials, starting from that they often can't tell the difference between brass and copper till that they call everything SS that is heavier. They take what the suppliers/manufacturers tell them as specs. Better to grow an eye for it. There've been many mistakes, many times about materials since I've been buying stuff but I wouldn't say, "they are lying". But I learned, (when it's about electronic stuff) you can never be sure what's underneath the plating/painting ;) I happened once to sand off the paint from a box which was told SS and found some cheap, easily tarnishing (though sturdy and heavy) alloy underneath. It happens, oh well. But I wouldn't repeat the experience, hehe.
Thank djvillan for the reply. I had a slight remind that it wasn't a generic clone. Never mind, those glasses will be good for the Gear itself ;)
