    It appears to work OK, and I did not have to return it for repair, if you know what I mean..

    This MFJ-913 works great on my 80,40,20 OCF but only up to 40 meters. The swr is great at 80 and 40, just a touch of tuning is needed at 20. But now my feed line is radiating on 80 meters after only a week of having it up and is causing rfi in the house. Im only running up to 100 watts. Probably just a quality issue im guessing.

    The UHF output was misaligned and fixing that isnt easy as you cant remove screws or take this thing apart in any reasonable way. However, performance of this balun is pretty good with multiple wire HF configurations.
