after the wash it took me about 10 minutes to get that glass taken off the chamber, some gorilla must have put the Siren together because the top flat o-ring (the white pad) at the top of the glass was put together so tight that the whole pad/o-ring was inside the top of the glass tank and seemed to be almost glued to the glass itself. I ended up taking a good 10 minutes with my pocket knife just to get the white pad/o-ring gently scraped off the inside of the glass, none was on the top of the glass and I worried about vacuum leaks. I replaced the top white pad/o-ring on the top of the glass with one in the spares bag, and off to building I went.
Same here when I first got it.... except it was the bottom o-ring that was like melted to the glass.
Tore it up good trying to get it off... wasn't happy to start off down 1 o-ring ha!
Just took it apart to check on the coil/wick, o-ring sorta stuck to the glass.
Guess it's just they're so soft and thin...? No damage though

Was thinking I must need at least a wick change after 60ml (twice my usual time).
NOPER - just barely a light tan streak. Amazing.
