My pair of Tifosi photochromics stretched out and didn't stay on my head well...then they'd hit the floor and the lenses would crack right out of the frames. Their range from light-to-dark is not as broad as the ONs, either.
I've had a similar experience with these glasses. They just don't seem to be really well made and while I find the light-to-dark range mostly functional, I do often find myself wishing they would not darken as much as they do under certain circumstances and when I've worn them at around twilight, I find them too dark.
I've not tried any other sunglasses of this sort though, so I really don't have anything to compare them to.
