I have/had one. It "seemed" to work fine out of my V3. I would NOT work out of my Panasonic SV-3700, but DOES work out of my Sony D-10 Pro. It would NOT work out of a DAP1 I patched 2 years ago, and I experienced some random weirdness with it a number of times, coming out of various gear.
Being that I would ONLY use it out of my V3 now (that I have my own rig again as of last XMas), it would "probably" work - but there's enough anecdotal evidence from other users that have tested this thing damn near to DEATH, to tell me that it's just too inconsistant to trust in anything but limited circumstances.
I now have the Hosa AES & SPDIF boxes for those RARE circumstances where I might find myself patching someone elses rig (like not being FIRST OUT on a board patch)...
