Hali Zoli,
Seems me that the grips are to short (for me with ca. 4-5cm shorter as wished) to have enough stability & force for driving out a fixer screw...
As kit is good one selected system, but a category smaller as I would buy for general PC mountings.
Greetings!

I normally get those 'universal screwdrivers' with changeable bits (tips) for various use. Usually, this lets you get 100 different tools and the money only goes to producing ONE Handle, rather than 100 handles (grips) - so it's usually much better value and quality for money.
