As I have a brodit car holder, I wanted the phone to be easily removed from the case. The problem was the case grips the phone a little too well, so a bit of shaving of the corners relaxed the grip enough to easily remove the phone.
By the on-off switch the plastic bar split, but isn't really needed so trimmed this back for a better access to the switch.
There is a magnet for the clasp which has a sticky label over it, this comes unstuck and moves, so a bit of glue required to hold it safe.
Other than that, I now have a great case that does the job for me.
