Looking through a 6.3mm Plossl suuuuckkssss. More trouble than it's worth.
u/Gregox is right. Orion literally just slaps their brand on white-label eyepieces.
This line of eyepieces look familiar? https://www.amazon.com/15mm-20mm-Orion-Expanse-Eyepieces/dp/B0000XMXX4
Yep, it's the gold lines, with Orion's branding applied. These aren't "originals" with gold lines being a knock-off, these are gold lines. Gold lines are generic white-label eyepieces that have been sold under many brands: Astromania, Svbony, Celestron, Orion, Agena, Sky-Watcher, and many, many more.
The gold lines definitely aren't perfect, but for their price, eye relief, apparent field of view, and the quality you do get, they are a good value. The 9mm especially, but also the 6mm.
