The product itself was very smooth and tight.The center worm screw assembly was missing.I contacted seller, and problem solved immediately.Great seller.
Unbelievable price for such tight tolerances! Good product!
I ordered 3 sets of these rails and ball screws, they arrived sooner than expected and the seller was quick to answer questions. The rails and ball screws are very well made and have tight tolerances. I will buy from them again.
