I find, unlike all the other attys I use, Ego-Ts don't die slowly. They just pop all of a sudden and are dead. Might be because I am using all variable gear, but I haven't had an Ego-T slowly die or give any notice. One minute its vaping nice, the next I feel it "pop" and its dead.
As an aside, I have a LR Type A that refuses to die. I switched over to Type B and all variable gear (which makes LR useless) over 3 months ago. This is my only LR heating element (gave away or experimented on to death everything else) and every so often I use it and try to kill it. It was one of my first attys, so I used it daily for about a month. I've dry burned it, ran it at 12 watts (on my Darwin) and it still vapes. I crushed it testing to see how much pressure it could take (not much) and used needle nose pliers to decompress it, it still vapes (but doesn't wick well at all, lol). I think its haunted by superman's ghost.
