Review on 🔵 Blue 3.5 Inch HDD Hard Drive Caddy/Bracket for Optiplex 390 790 990 3010 3020 7010 7020 9010 9020 MT SFF Computers/Precision Workstations - Pocaton by Zack Block

If it's not an original item, you'll never know. The one I received still had a good amount of flexibility. I have broken several of these braces, either because they become brittle over time and break when bent to insert or remove a disc, or because the pins slip out of the plastic and break the small retaining tooth. I didn't feel like there were any issues with this Caddy anyway. I would (and probably would) buy this again.
