Heavy, solidly built unit.
Heavy and strong. These would be an upgrade to anyone looking to update their CNC. I couldn't believe the size and weight of these things. Included all parts and was a great value when you compare to other suppliers.

Great ball screw set
Great ball screw set. It's not aerospace grade $500 set but it's fine for what it is. The screw rod is SUPER HARD and I would try to design my project around the available sizes and avoid cutting it. Well packaged and ball screw rod and ball screw is double packed within a cardboard tube inside a cardboard box. The bearing blocks, aluminum mount and screws are well packed too.

Just ad I expected.
I lengthen the x-axis on my CNC with these. They are compatible with other ballscrews I had purchased previously. I expect no problems.

Inconsistent Parts
Ordered 3 of these from the same seller for a CNC upgrade. All of the parts were received. The blocks were not identical which caused inconsistency. The bearings were not seated fully in some of the blocks. One screw was slightly longer than the others. They seemed like a pretty good deal, but you get what you pay for.

pleasantly surprised at the quality
Very happy with this ball screw. The packaging was great and the screw arrived undamaged. The shipping said it could take a month, but it arrived in 3 days!! I was hesitant to order because the price seemed to good to be true, but after opening and assembling the ball screw I'm very very happy with this purchase.

Quality just not there even for Chinese manufacturing
First off the lead screw arrived bent. Wasn't sure if bent shaft occurred during shipping or manufacturing, but after a few hours with my hydraulic press I was able to get it straight to my likings. Then once connected to my CNC the ball screw nut was making sound similar to a garbage disposal at low rpms of the lead screw. Taking a closer look at the ball nut I found I could easily move the nut up and down several thousands with just my fingers. Taking the ball nut apart I found the ball bearings inside easily seen to be different sizes in diameter with my naked eye. Ended up order a new ball nut from a different supplier to get my CNC going.
