PROs
-Preamps are really good, quiet and have lots of gain, more than enough headroom, for reference 60% gain can drive a Beta58 loud enough.
-There's no other option on the market that have so many I/O and in a desktop interface size
-there are a lot of buttons and some of them are configurable, convenient for working quickly
-2 pair of Speaker out and 2 headphone out is great to have, though there is only 3 monitor mixes (good enough to me)
-Headphone out is powerful enough to drive K702 and HD650 at 50-70% volume
-Bluetooth is handy, very happy to have, but do not expect the quality anywhere close to the wired inputs
-USB cables that comes with it feels sturdy and looks cool.
-work smoothly on both my mac and PC without any issues at all
-Love the USB hub function, especially if you are a macbook user like me
CONS
-It can get a bit warm when in use but acceptable.
-Latency is not as good as the thunderbolt interfaces, it's USB 2.0 afterall
If you want an interface with 4 quality pres, 8 analog input, expandable, portable and do not need DSP, this is a very good option
