We've had great results from your silicon nitride probes.
- S. Schanhals, Eaton/Saginaw, Saginaw MI
I put the silicon nitride styli through the paces. Previously, I wore a flat spot on two ruby probes. I'm still using the silicon nitride styli. I can see no wear, even under magnification. I plan to order silicon nitride tips as standard. Thank you for introducing me to them.

I have been very pleased with the service from Q-Mark and plan to come to you for all of our CMM stylus needs.
- J. Beaty, Bombardier Motor Corporation
We had a problem with ruby balls picking up dirt and chips. We eliminated that problem by switching to silicon nitride. We will only buy silicon nitride tips from now on.
