Successfully connected to the video receiver, the frame rate is good, but the video color is not the best. The device gets very hot (enough to burn itself) when you turn it on and will likely need additional cooling. I noticed that the polarity on the connector is reversed compared to the mating connector on standard batteries (Elite and Nine eagles.walkera batteries work with no change as they don't use standard polarity). I haven't flown it yet, but I assume it works. Conclusion: It's worth the money and if I don't have a problem I'll probably buy another one.
