Parts were direct upgrade for ender 3 pro. Parts are okay. Packaging was crappiest try i have ever seen. trapezoidal rods were together in single bubble wrap and they were rubbing each other. That resulted really janky movements. also the end of rod was damaged so that the ball bearing in the top did not fit. Also stepper motor was moving inside package and part of the connector was broken. Y cable in the package was good and it split the one stepper output for two motors. that was good thing. Seller tried to rectify the issue, but we didn't have common language no negotiate really.
best quality kit
