Pretty sure its been confirmed that "Spyder" and "Anzo" assemblies vs their "knockoffs" are actually 100% identical and made by the same Asian manufacturer on the same assembly line.... just different stickers and different price tags on the box getting them direct vs. getting them thru a US badge-engineering reseller
I keep thinking about buying the spyder assemblies but am worried about the light output. $400 ain’t cheap to drop on seomthing i don’t know works.
