It's quite a nice mic, but it's quite limited in terms of lifetime. Lasted me about 9-10 months before the sound quality started going down and eventually the picked started doing some weird things. If you can't afford a good mic for your PC and need something temporary, this is a good solution. Don't expect to keep this for a couple of years though.
Good clip-on mic however the clips are not very good. I wouuld have preferred a spring-loaded clip so I can clip it to my shirt. My Sennheiser HD 598 headphone cord is very thick and the microphone clip is not large enough to clip on to my headphone cord.
