Summary: I did not use the tool to adjust, just saves time on set up. Do not over tighten the set screw it will damage the threads and make it very hard to readjust.

Yes, I recommend this product.

Summary: Big difference in the drag on the bearings. I set them up without using the setup tool, but I can see where the tool would make it a lot faster. I would recommend marking alinement once set.

Yes, I recommend this product.

I plan on buying enough of these for 3 hobby stocks!
