The lift is great, but it's not the last word in the world of lifts :) It is worth knowing that there is no brass clamping ring, no millimeter scale and no micrometer gear. The tube foot is not interchangeable with other GSO (two-inch) Crayford alloys.
It's good to understand that the design of the Crayford type lift (it's worth taking a look at even Wikipedia!) Has this specificity, especially when anodizing as in GSO lifts, that anodized coating, when in contact with a roller bearing, may sooner or later reveal two traces - like paths along which it comes to the lift sleeve. This may already be in the new statements - and it is not a defect, it can also be almost invisible. We warn you that this is simply a feature, not a disadvantage of this design.
