Converting 48v phantom power into "clean" gain is ok, but
compared to Behringer UMC202HD's midas preamps, this thing is noisy. However, the noise seems to be not the typical high pitched whine of preamps, but rather a little bit lower one.
You also need a patch cable to connect it directly to the interface, because the male part has a very thick layer of metal around it and would siply not fit. Respectively, if you're ok with plugging it in the back of the mic, then no extra cables are required.
Conclusion:
If you have a decent enough preamp in your interface you dont need it. If you dont, then you probably will not care about a few extra db of background preamp noise. In the end, it does what it advertises to do, and for the price, it is enough.
