Been using the Dejero this season for NFL coverage.
The store-and-forward is awesome. Clips get back in very nice HD. However, w/ our system, producer back at the mothership has to play out and re-record those clips...but still pretty good-looking HD.
Live operations have just one little weird bug w/ our system...the video sync is slightly off. Not lip-sync, but the vertical hold. Nothing a quick reset at home won't fix, but it seems to happen every time.
There's a jack for IFB support...don't know how that works yet.
Dejero's phone support for their box is outstanding. Always there, always helpful. Sure, there's an accent, but they're great guys.
Recommended...but be wary of bandwidth issues. In a full NFL stadium, you'll get knocked off the air due to all the cellphone usage.
City TV in Toronto did some cool moving bump shots with it and a GoPro, totally blowing some anchor's mind...
