AVID Digidesign Sync I/O Model MH040 Rev K pulled off the rack from a working Pro Tools HD 3 system running Pro Tools 10 HD. Sync case has wear and tear visible and some dings and scratches from use. Works.
In the "Details" they should have added that the front panel left-side blue plastic is broken comes loose and pulls out and hasn't come off yet.
We are too far to send it back - and it is working, so we'll see over time how it goes.
Good luck,
Japan
