Great R2 upgrade - much stiffer than the rod that comes with the unit ensuring angle consistency. Should be standard on the R2 but I can understand the incremental price increase could turn some buyers off. Just note, if you travel with the unit, the standard rod slides right through for quick take down while the Precise angle adjuster requires removing four mounting screws.

This is a great upgrade for the R2! It is completely solid and has no wobble like the original rod had even though it was minimal. Also, it is so smooth and easy to adjust the angle now. I noticed that my edges look flatter after changing to the precise angle adjuster. Nice job Hapstone!

Absolute must have for the R2. It is simple, accurate, and easy to use. Also, Hapstone's customer service istop notch. I also have one of their premium diamond stones and one of the cbn start stones, both of which are excellent.
