Straight and true to size

This was packaged very very well to ensure it arrived straight and correct. It fits and works well without resizing. The only drawback is that the delivery took a long time.

Pros
  • Industry and Science
Cons
  • Very Expensive

Don't buy a bent bar!

This product is terrible. The only thing these rods should have is smoothness, correct dimensions and most importantly straightness. It goes with everything except it wasn't straight so I can't use it. Please do not buy this product.

Pros
  • Linear ball bearing
Cons
  • Not sure

Worked due to my craftsmanship

Came slightly bent, took care of it with differential lock and 6mm hardened steel tube on my rod and slowly rotated it after heating it by moving the hardened steel rod down . I sanded it down and applied it to my 3D printer as I needed more support for my gantry. Needless to say I needed it so I kept it, but if you don't have the skills to fix what you have, buy it somewhere personally.

Pros
  • Powertrain products
Cons
  • Could have chosen a newer model
