Sturdy construction

Feels durable in the hand. The metal is thick and does not bend under pressure.

Very useful tool

Works well though requires care when removing tight knobs. Good value for the price.

Good but specific

Only works on standard knobs. Did not fit my vintage set-screw knobs, but works as advertised for modern gear.
