Curious if anyone has tried this out:
https://centrance.com/store/MixerFace-R4R-Mobile-Recording-Interface-with-micro-SD-Card-Stereo-Recorder-p121815331

$449 with microSD recorder
$499 with microSD recorder and XY mics
$349 interface alone (no microSD recorder)

Curtis Judd reviewed it here:

Pros:
Decent pre-amps (comparable to Zoom F series it seems -- except on max gain, see below)
Compact (slightly smaller/lighter than Zoom H4N)
~6 hrs with 2 XLR phantom on built-in Lithium batter (or longer with USB C battery pack)
Simultaneous recording to microSD and phone/laptop

Cons:
no LCD display (no indicator of remaining recording time, for instance)
max Preamp Gain of +53dB
2 LED monitoring
microSD
no mic in with plugin power

I've been looking for a good quality, compact 2 channel mixer recorder with decent battery life for concert/field/VO with dpa 4060s, MKH 8040s, other mics. My MixPre-3 arrived yesterday, but I was disappointed by the unreliability of the USB-C connector. Came across this and now weighing the options for highest quality, most-portable 2 channel XLR recorder.

Any one have experiences with this unit?

jerryfreak:
seems cool though im not sure why you would need to double up to microsd and phone (in the field), have never seen a microsd slot fail to write

do you need a realtime mix-down or just 4 channels?

aaronji:
There are a lot of folks here using the USB-C on the MixPres successfully, so maybe one of them has some advice.

There are also a bunch of alternatives. I have been using the 8 AA sled for my MixPre-6. With two channels of phantom (2.8 mA draw per), two channels of board feed, and the mix, I have recorded for a bit over four hours with only one click on the battery indicator going down. That’s with Eneloop Pros. A friend uses the L-mount sled and loves it. Great pres and loads of gain...

Thanks Jerry.

I agree, backup/redundant recording is not essential in most cases. The ios/android connection could be useful in other ways (i.e. to see the waveforms, write metadata, see how much space is left, etc) since the device itself doesn't have a screen.

I don't need realtime mix-down or 4 channels.

I'm looking for something in between my Sony M10 and my Zoom F8: something very small/portable with great battery life like the M10, but can accept 2 XLR inputs with good quality preamps. My Zoom F8 is just a bit larger than I'd like for some field recording projects I have coming up.

So I've been looking at handhelds (Zoom H4/5/6, Tascam) trying to find something like my M10 but with XLR inputs vs Sound Devices Mixpre-3/6, something like my F8 but smaller.  It seems this device might slot in somewhere between them, but I'm curious to learn more about it....

That's helpful. My experience with the included USB C to double A cable was disconcerting (the device flickered on/off, or the connector itself separated after minimal jostling). But it could be a bad cable.  4 hrs on the 8 AA sled would plenty for most of the situation I have in mind. Hmm.
