Good Value
Quality is good, but threads were a bit tight initially. Needed a tap to loosen them up slightly.

Sturdy Spacers
These are solid. Used them on my CNC router build and they held up perfectly under vibration.

Perfect Fit
Fit exactly as expected on M4 bolts. No play in the threads and the length was consistent.
