Essential and excellent; could use padding
This set of drivers is an asset to the bench, as it covers virtually any saddle adjustment scenario.
The only thing I would suggest is some ‘padding’ to protect finishes in the event of a tool drop.
I encased my sets in transparent heat shrink tubing, end to end. Still easily gripped, as the two tubing sizes I used hug the shape, plus have grip by their nature.
Highly recommended tools.
