If the assertion here is that Kobo devices are fragile: they're not.

Our first two Kobo were purchased in 2018 and both have been on every business / personal trip since. I don't particularly go out of my way to protect mine, I have the stock magnetic cover. Other than the edges of it wearing, that's the only visible "damage". My kids have had Kobo since 2019 and they take them everywhere. The Kobo devices are not fragile in the least. I worry more about them being left behind than breaking them.
