A part of the review has been auto-translated.
Please don't waste your time on these. The machining quality of the lead screw is appalling, with uneven pitch all round. This is evident through cyclic binding with the lead screw nut. This problem was evident in both pairs of lead screws and nuts I had purchased, so this isn't mere coincidence. In fact, other nuts also bind on these lead screws, whereas the supplied nuts don't bind with other lead screws. If you buy these lead screws and install in your printer, that axis will experience massive binding and wobble. You are going to hurt both quality and durability of your 3D printer by using this product. Avoid this like the plague.
Everything was OK!
