Reviewer Kit

Early in production developer hardware, Microsoft would loan a specific unit to game journalists. These units would be used by the journalists to review a game months or weeks before the game reaches its retail product milestone. They came in the same charcoal gray case as Development Kits but lacked a Sidecar, having a standard 20GB HDD in its place. These units also had a small square sticker around the rear I/O that reads "Reviewer Kit". Although being only production Xenon motherboards, they could also be sometimes seen with a secondary serial barcode sticker that would commonly be found on Beta Hardware. These units were quickly phased out because of Demo Kits.
