Perfect
It's been a little over a year since I installed it (no problem for a Zalman Z11 plus) and it seems to stand the test of time, I don't use it often but it feels solid, no play in the hinge and obviously all metal.
I don't hear any noise when a drive spins inside.
Unlike my sata usb adapter, SMART data is detected directly.
There is a blue light when a drive is present and a red light when there is activity.
The lock is a bit of a gimmick I think, I feel like if I pull hard it would break, I don't use it anyway.
I'm not using it anyway. For backup or long tests it's perfect as nothing is lying around on the desktop, there's less risk of the hard drive being smashed.
