I've just been taking apart yet another gadget that looks like it has 4 big
screws securing the case, only it doesn't. The case is also held down by
the dreaded hidden plastic clips, the sort you need 15 flathead screwdrivers
to pry open and usually end up breaking some.

I'm sure there must be a better way. Sometimes I've used a cake slice for
trying to flip a row of clips at once... but it still damages the plastic.
They must do this sort of thing regularly at the factory... is there a
proper tool for it?

Cheers,
Theo
