RE: First impressions: Bondhus ProHold ball drivers
I did spin the handle on one of mine, but overall had great luck. I use two of them to assemble one plane and a third to assemble another. I just put a red pin stripe on the handles of the two used for plane one. And a orange pin strip on the driver for plane two. Makes quick work when reaching in the tool bucket no matter if I can read the size or not.
