Overall, a good investment in print quality. Bought for my 3D printer (Mendel90) to replace an 8mm Z-threaded rod. The lead screws I received were straight, 4-start and contrary to one of the answers to the questions (but matching the advertised product) had a pitch of 8mm (the nut moves 8mm for one full turn of the bolt). The lead screw finish is somewhat lacking; it is not polished and there were slightly rough edges during manufacture which caused a little resistance to the nut which i coated with a light layer of grease. This can lead to accelerated nut wear over time, we'll see. For €15 I didn't expect it to be perfect.
