The blue plastic tool broke when I removed my Logitech diNovo Edge keyboard, so watch this really is not strong but probably not to be used as I did. Do not push the screwdriver because the metal is of very poor quality, and do not use these screwdrivers for other screws than those for which they were intended (I broke the tip of mine that way) . After, at this price point there really is nothing to complain about, we know what to expect.
