Customer Reviews for Ball screw 1Set Anti-Backlash RM1605-350mm-C7 BR Coupler CNC Router Amazing

Product itself may be great but I got a defective lead screw the head does not move at all. Just stuck in one spot. I tried contacting the seller and seems like they keep sending me the automated message asking me if I want to replace and I’m keep saying yes. But I keep getting the same message over and over again.Update: Changed the ratings to 4 stars. The vendor sent the replacement. Item works perfectly. Will buy again if needed.

Very Strong cleaning tool, doesnt seem like it does anything when you turn it on, but it works.

Works very well, easy install

This Anti-backlashed Ball Screw is one of several purchases made over the year. You just can't beat these prices with a lead screw.

C7 is a sweet spot in cost/precision for my project. The linear drive works as intended with great precision. Pretty happy with the results, and bought three more
