Works fine. Plane insert plate. Keep the quality.
Plate is flat and clean milled. The groove for the spacers is very precise (5.02 +/- 0.01 mm) but the spacer ringes itself are not parallel (between 4.81 - 4.90 mm). The guide bushing is very clean turned and a good upgrade. Shipping is very fast (with working tracking number). All in all a good value for the money.
