Behringer UMC1820

After using this piece of kit for a few years now I've had to change my review.
Sound quality is very thin. I don't know if I have a defective unit or not but there's very little bottom end on any of the monitor or headphone outputs compared to my other interfaces, which makes it very challenging to apply the right tonal balance to my mixes. The mid to high frequency detail is very reasonable however.
Build quality is average. All knobs feel robust enough but both headphone controls started crackling within months of use. All of the connectors have been quite solid. No audible crackling when twisting or wiggling cables.
The software is very basic. The ASIO driver is buried several pages deep on Behringer's website but once it's downloaded and installed it works really well with good latency and no audible glitches.
All in all, there's good points and bad points. I think once my budget allows for it I'll choose a higher end manufacturer but for now it's doing what I want...mostly. You get what you pay for.
