Let me start by saying this little adapter is a game-changer for anyone dealing with rusted metal or woodworking projects. I recently used it to restore an old metal gate, and the 80-grit wheel ate through rust like butter. The non-woven wheel leaves a surprisingly smooth finish on stainless steel too.

The good: This thing is built like a tank. The heavy-duty construction handles serious abuse, and the multi-size sanding belt compatibility (20mm/40mm) makes it versatile. I particularly love that it comes with five different grit belts (60-600) - saved me multiple trips to the hardware store.

The not-so-good: Compatibility issues are real. Like several reviewers, I had to MacGyver a solution for my DeWalt grinder. The protruding bolt heads require a spacer (not included), and getting it mounted securely takes some finesse. Once it's on though, it stays put during operation.

Pro tip: Have some washers and a band clamp handy during setup. The effort is worth it - this adapter outperforms purpose-built burnishers costing three times as much. Just know your grinder's specs before buying.
