Fairly solid construction, the plastic knobs aren't incredible but they have a good resistance to them and feel like they can take some punishment well above normal use.
Its quite light, and mostly plastic although the outer airbrushed metal frame makes it very sturdy and gives it a great appearance, and a feeling of quality well above what i would expect for the pricepoint. (Under 80€)
My only issue stem from a minute hiss that wasn't present with my previous card nor my PCs own soundcard. The hiss is around the midrange and won't be detectable in use anyway. But it might be noticeable when no sound plays.
On a positive note, the ASIO is great and the desk appearance is incredibly clean. I'm very happy, but do keep the beforementioned things in mind.
