I suppose I haven't read every single thread on the whole ECF from start fo finish.... but I have read most current ones and have been reading for years, trying to stay current day to day.
And yes, this really is the first time I have heard about a sticking button. Can you link me to the sticking button threads for the Twist please?
Are you another YouTube name dropper? lol.
I have sturdy devices like the Provari for eg.... but still use the Twist.
The search box works pretty good for stuff like this. It is something you should be aware of since you're a twist user. -- Though, I sort of think that it's how the buttons get placed during assembly. If your buttons are good now, they'll probably stay that way (as long as they don't have a direct impact on the bottom or top from a fall that would move the switch assembly). If the edge of the button is close to the casing and can slip under it, you will probably end up having it stick now and then.
Anyway here's one and here's one that got dropped and here's one the cat was vaping
As to name dropping: I just figured that GrimmGreens' review would be the easiest to find if you were so inclined to look for that information. I could have linked it, but figured you'd be OK finding it on your own.
While I'm at it, just in case you ever do experience a stuck button with one of your twists, Steel Jan made a nice repair video.
