Lab Seconds, Factory Seconds or X-Outs are discs that may have slight cosmetic flaws from the factory. These minor flaws do not affect the flight of the disc. These flaws may include stamp dropouts, mis-stamps, etc.
The Tempo by Axiom Disc was approved by the PDGA on Jan. 30th, 2023, and appears to be a new putter/approach mold. A bit more overstable than the Entropy but a bit less overstable than the Zone by Discraft.
