Built like a tank, as they say. No problems at all with the hardware.
Software side was a bit of a chore for me though, took several days to get it set up. Could not get it to play nice with ASIO4ALL / Reaper, no matter what I adjusted (dropouts and weird noisy reverb effects), but I found an old Behringer ASIO driver on the internet which works well.
Would buy again: I would go for a higher model with more bits / kHz, but for now I am happy.
