Detail 02
You control the speed, so there is no risk of over-torquing a tuner the way a drill attachment can.
Detail 03
Meant to live in a gig bag and get knocked around rather than sit on a bench.
Detail 04
Cheap enough to keep one in every case, which is the point — the tool you lose is the one you needed.

Product questions
Straight answers to the questions shoppers most often ask about this product.
It is cut for bass machine heads, which are larger. On a guitar the cup sits loose and tends to slip, so it is not the tool for that job.
No. This winds tuners. You will still need cutters to trim the string ends after tuning up.
It is a hand winder. Turn it yourself and you keep control of the tension, which matters on bass tuners.
If you change your own strings, yes. Winding four bass tuners by hand is slow, and this cuts a string change to a few minutes.
