I'm indifferent about this interface, but it does the job. Lately, because of Windows 8.1, I've actually experienced some weird issues with not being able to listen to external audio while I'm using the interface with Cubase.
I liked it at first but I have since changed my mind. Don't get me wrong it gets the job done. But might I add that you get what you pay for. It would be better for someone to buy a 1 or 2 channel preamp that rocked instead of this guy. Still did me a lot of work.
it is probably the cheapest featurerich interface you'll find. and it does a great job at it. the included drivers gave me some trouble, but Asio4All did a better job.
The preamps are clean and quiet, what more can you ask for. It even has some extra input jacks so you can hook up an alternative(better) preamp.
one complaint: the direct monitoring via headphone gives too low signal to be practically useful for overdub recording from pc. i have resorted to using a behringer ma400 headphone amp with mic and monitor level mixer.
