So how does this work if you live in a hot part of the world, and say, you leave your notebook in your car for the day.... does all your work simply vanish?
I'd definitely be interested in real-world testimony but the linked article says that the "erasure temp" is 60C/140F. Your work would hopefully not be lost forever, though, because it should reappear under -10C/14F. (Along with all the mistakes you erased, I suppose)
I've lived between Costa Rica and California with these pens as my primary note takers and nothing like that's happened yet. Surprised to hear so many horror stories actually, maybe I should be more careful haha
