Cheap construction, almost breaks during install, does NOT fit 12.5mm drives
Item does NOT fit the 12.5mm drive. Removing the bottom caddy is difficult because there is interference between the cage and the caddy. It almost breaks every time you pull the tray.
I would not recommend buying this item based on how poorly it is built.
The only oddity is the blue upper drive indicators are dimmer than the lower drive indicators, by 50%.
My built-in Drive Activity light [on front of PC] still works fine though.
