Question CEntrance MicPort Pro USB preamp

Does anyone have any experience with this USB mic preamp?

I've been searching for something like this for a long time. I would like to pair this up with an ECM8000 and use the setup on a laptop with TrueRTA.

The specs look good.

Sample Rate - 24-bit/96kHz with optional 44.1kHz, 48kHz and 88.2kHz modes
Audio Input - Female XLR
Audio Output - Stereo 1/8 headphone jack
Power - USB bus (no batteries or external power supply
Phantom Power - Switchable 48V (internally generated)
Frequency Response - 20Hz-20kHz +/- 1.5dB (min. gain)
EIN - 121dBV (A-weighted, 150 Ohm source)
Dynamic Range - 103.5dB (A weighted, min. gain)
THD+N - 0.01% (-0.5dBFS, 1kHz)
Input Impedance - 5 kOhm
Maximum Input Level - (full scale) -9.5dBV (min. gain) to -45.5dBV (max. gain)
Maximum Output - (headphones) -7dBV @ 16 Ohm load, -1dBV @ 32 Ohm load

I could buy this and the ECM8000 mic for under $200.
