Finally got around to using this on my older retainer system spinner and the fit is perfect, no wobble or slipping at all. The simple design does exactly what it's supposed to, which is all I really needed from it.

My spinner had a wobbly bearing for weeks, and this little wrench made the swap a five-minute job instead of a frustrating fight with tweezers. The head fits the standard retainer system snugly, no slipping or stripping. Exactly what a simple, functional tool should be.

Finally got this to swap out the bearings on my spinner and it took all the guesswork out of the process. The prongs fit the standard retainer system perfectly, so no slipping or stripped threads like I've dealt with before. Solid little tool for something so simple.
