PROS: I love that its made from metal, feels very good in your hands and provides a sense of confidence. XLR mount is very stable and the knobs feel secure and rigid. Features give yout everything for small studio work. 10 points for design and overal exterior build. Thats all for the PROS.
CONS: For WIN users: what I hate, as many other people, is that Behringer doesn't provide their own dedicated WIN drivers for UMC22 and you're left with Asio4all which is outrageous! Asio4all is not even working correctly on WIN10 after certain update some time ago. If you want small buffer size, Asio4all is going to crash on you or make bad noises eventualy. Thats a shame, because I know that some time ago UMC22 worked flawlesly with Asio4all and provided very small latency. Anyways there are many recommendations to use older Behringer drivers from other users (BEHRINGER_2902_X64_2.8.40), which you can google. It works for many with less issues Asio4all (with the "rapid" option selected in the Behringer drivers settings), but Behringer themselves don't recommend it anymore for some reason.
I should point out, that I had my unit returned for money back. One of the reason is the driver issues, mentioned above, which leaves your very well built unit practicaly unusable. Another reason lies with white noise levels on MIDAS preamp. It was very audible, when I cranked the mic gain pass 70 percent, but I only got minus 20 dB (or less) on my DAW, so in the end you are left with bad noise on your recording after final mixing. I'm not sure if it was drivers' problem or a hardware fault. This may not occure on every Behringer unit, because I also tested another UMC22 unit of my friend with no issues whatsoever, but I've read a lot that the same problems as mine are very common.
That said, I think it could still be usable for beginners and you could get good results from the interface on the condition that you got a working unit (with no noise issues). Also, I should note that UMC22 is better to be used with MAC and not WIN systems, because of the serious driver issues (lack of them) with WIN10.
