I had my custom case for around a year now, with nothing really happening to the case.
Never dropped my phone, never dropped anything on it.
The case just fell apart, the sides release from the back cover. Looks to me like the glue holding it together failed. On purpose?
Doesn't matter, cause paying over 50 € for a phone case with this quality. Nope thanks, I stay with the old 10€ cases I had in the past, which laughably lasted longer.
In the EU this would even be covered by a 1 year warranty but the 6 months from casetify are for a reason it seems.
