Review on Enhanced Performance: CHoiKWong Carbide Rabbeting Interchangeable Bearings by Tay Fair

Allen key provided to replace bearing was the wrong size - it appeared to be imperial although it should have been metric or a half size different which is the only thing Reason for losing stars. I just used and installed one of my hex kits. But otherwise it's a great set. The knives cut very cleanly and the bearings are smooth-running. It was perfect for my application. Highly recommended, just a BYO Allen key.
