I bought these to repair a Bergeon watch waterproof tester that originally had an aluminum rod that had corroded. I figured to upgrade with stainless. I had to cut it to a shorter length no problem I thought took it to my bandsaw. All the blade did was make a small scuffed spot. Had to cut it with an abrasive wheel. Then I had to drill a small hole in the side for a tiny roll pin. I destroyed several cobalt drill bits before giving up and tig welding a bit of rod on the side. The rods I got were perfectly straight.

Not much to say about these, they're exactly as advertised. Perfectly straight and dimensions are accurate, linear bearings run smooth on them

There isn't much to write in a a review when the product is exactly as described by the seller. The rods were cut to the length described by the seller, the correct diameter, etc. No issues whatsoever.

I used these rods to refurbish Y axis assembly of my Prusa MINI and so far they perform fine. They arrived in a sturdy cardboard box, which I appreciated, except both rods were in one plastic sleeve, thus touching each other. It would be better to have the rods separated to prevent any potential damage to precision ground surfaces. Luckily, I didn't notice any damage, trimmed the rods to proper length and they work fine so far.
