Quality:
Official Roland product, though it's nowhere to be seen on their website. Real odd as I believe it's a must-have for many and real-nice-to-have for some.

Value:
Kinda on the spendy side (IMHO) but what are ya gonna do?

Support:
No documentation (tsk-tsk) which is a pain because the manual clearly states to not take out any screws (other than those shown in tha manual to add an extra FX card). And here you now have to take out over a dozen screws on the side of the unit to fit the rack-ears. I don't know about you, but I get that feeling of dread, like you're gonna hear something drop inside.

Overall:
Most (if not all) adverts for this product state that screws will be included with the rack ears; not so. You'll have to recycle the ones you take off the DAW itself. You have to be careful because by re-using those screws without the units side panels, the screws now go further into the unit than they did originally. One of the screws clearly butts-up against the units's selection-wheel, so I omitted that screw in order to not damage the unit. Also, because it fits into a rack, it is highly likely that you will not be able to use the CD-RW with these ears in place. They are therefore just good for transportation. But everything fits beautifully.
