I have 2 Mezz cues. The quality is exceptional. Even the thread timing is exactly the same for both when I attach an extension in the butt. Could be a coincidence. But my experience with Mezz is that nothing they make is by chance.
They do that a lot in the Philippines. I've seen their own versions of virtually all popular joint pins. 3/8-10, 5/16-14 and even Uniloc QR that either fit too loose or too tight into standard jointed shafts and joint protectors.
