Good value
Mostly good quality screws. One bin was slightly lower on count than expected, but overall great value for the price.

Great organizer box
Love the compartments. Makes finding the right screw much faster than my old mixed container. Highly recommend.

Excellent assortment
Used this kit for my 3D printer assembly and general repairs. The variety of lengths is very helpful and the box keeps everything organized.

Soft metal
Stripped a few heads easily when applying torque. Good for light duty but be careful not to overtighten.
