I purchased the RUIXIN PRO 8 Pcs Diamond Knife Sharpening Stones for my RX-008 knife sharpener, and they worked exactly as described. The stones are well-constructed and properly glued, unlike some other options on Amazon that are poorly made and prone to breaking or delaminating with basic use. This set feels solid and durable. While I'm not completely certain the grit sizes are precisely as labeled, they seem fairly accurate and perform well. These stones worked well with the RUIXIN knife sharpening system, and allowed me to sharpen eight kitchen knives quickly and get great results. My only suggestion for improvement would be the addition of a 6000 grit stone for even finer finishing. Overall, this is a high-quality product and a worthwhile purchase.

They work, and the price is right. If you're looking for cheap stones for a cheap sharpener, these work great.

I ordered these for my Ruixan sharpener. They work great. However, do not leave them soaking in water for more than a few hours. The metal plate the diamond powder is attached to is plain old Iron, not stainless steel. So the plates immediately begin to rust and turn the water rust colored. Soak them before use but then dry them as thoroughly as possible. They seem to work fine even with the rust discoloration.
