Worked for exactly what I needed.
I needed a flex hone to clean up the inside of a Moen Positemp shower valve, when replacing a leaking cartridge. This worked perfectly to clean the corrosion and scale from the inside of the valve body, and left a pristine surface for the new cartridge to seal against. I’ve used these for years on engine cylinders, so I had no doubt it would do the job needed. These are a bit pricey, but it was less expensive than replacing the entire faucet assembly in my shower.

Best to use a bit of honing oil
I have several sizes of these hones. All work well. Best to use a bit of honing oil.
