Well, if we are talking about the stopping firing issue when not applying enough pressure...I have four of the 50's, and they have all done this, and behave exactly the same...right out of the box. Not saying they should be that way, but all the ones I have used have done this...they work fine as long as I leave constant pressure on the button, and none of them have gotten worse with use over time.
LOL
I have strong hands.
Trust me, I know how to press them down properly
No, thats not it.
As one is vaping, no mattr HOW HARD you press, all of a sudden there will be no juice, air only........once in a while.
But then it began to happen more and more over a few days until one day, it seemed to happen almost one in 5x
Up until that point, having it happen once in a while i didnt give it any thought and also first questioned if I had been not pressing it hard enough as well and accepted that must have been what i was doing.
But because I have the Delta II tank on mine, it almost felt as if does if you open up the air on the tank fully so I then thought it was the Delta...
Understand at first for a bit in time it happened infrequently enough that you dont give it much thought until later.
So one day this week it started happening 2 out of 3x and I was starting to get ...... off with it.
Went to bed that night as i always do and i turn them all off at night. I never charge over night and this one I took with me and when I went to turn it off, it wouldnt go off.....I was half asleep and again, you sort of wonder whats going on and blame it on yourself.
The next morning when I went to turn it on thehn it began to happen 1 out of every 2 hits and by now i knew it wasnt me......and within 2 hours it was down to happening all most every time so I took it back.
I was given a new one which I gave to my husband and i took his, the one hes been using periodically that i purchased the same day as i did the one I took back and i can feel it occassionally happening on this one.
Had it not happened to the first one, this one too i would just think I wasnt pressing hard enough here or there.
I am prepared for the possibility that this one might go as well, yet we have 2 iStick 20w that neither have had a problem with but I keep hearing from others as well its only on the 50w version.
I dont believe its a high majority of them but its out there and i am not the only one this is happening to..
EDIT:
Let me add that i am a heavy Vaper as I work at home and am not restricted to work enviorments but i have 3 great sets and the one i took back was not even my fav set up.....so it wasnt used daily or a lot but a few days before it went, I purchased a new one from FT, another brand, and my fav set up which was not the iStick was retired.
So 3-4 days before this issue came to a head, I started to use the iStick again otherwise i believe i would have noticed it much sooner than the 6 week mark
