good
Works just as described, great.
Efficiency is not great. We tested at 48V input and 12V/0.74A output. The input current was 0.25A,which translates to an efficiency of only 75%. Maybe this is why they don't say anything about efficiency and don't show the input current in the photos.Of course still better than a linear step down converter but not really good.
