Different year/model, but same experience with the same task: I really hate situations where the secret is "a suspicious amount of force", especially if there's no sufficiently trustworthy/detailed information showing that things can be pulled or pried in a certain manner.

IMO these are worth buying, they're quite cheap and trying to make-do with metal tools will cause more scratches and scrapes than you'd expect, no matter how careful you're trying to be.
