The Behringer C1U was my first ever USB microphone, and it served me well! It saw the purchase of my first interface, as well as my first ever attempts at releasing songs! It miked amps, it tracked vocals, worked with Audacity, Reaper and Ableton, faithfully for low price.
BUT it was not a perfect piece of gear. Toward the end of its life it began to buzz uncontrollably and feedback to the degree where I couldn't even do a skype call with it, let alone record vocals. It lasted a touch over a year, which was all I can really ask from a mic at this price. Well worth the money
