Summary: I got this refurbished for $10. At that price, I guess I can't complain. Sound quality is excellent, but the volume is very low. As a result, you need to put the microphone close to your mouth, rendering the webcam useless. Effectively, You can use video, or record audio, but not at the same time, at least not on windows 7 Video quality is about as good as a webcam from 2005. I don't mind that its not HD, but its grainy, and the colors look weird.
Summary: the video is OK in bright light with little movement, but add either a low light situation or movement and it fails miserably. I got this to upgrade from a MacAlly IceCam2, which is not HD, but gives far better results, mounts easier to an LCD monitor or laptop and is less expensive. The sound quality, however is quite good and I now keep it next to the cam it was meant to replace, as a microphone only.
Summary: I don't understand what good spec claims do if a web cam doesn't come close to achieving them in the applications under which it operates. I bought the Eyeball 2.0 to use with ichat and have not used it with any other programs. I have a Mac Pro with 12 gigs of Ram and a broadband connection. I tried using it running Leopard and Snow Leopard with the same results, from the moment The Eyeball 2.0 came out of the box it had slow frame rate issues.
Summary: I bought a Blue brand because I heard good things, however, this webcam is a piece of JUNK! The video quality is very low, and lags ALOT. The audio quality is OK but is very quiet. Don't waste your money.
Summary: Tried this on my Macbook Pro alongside the built-in iSight. The sound isn't really up to the quality that I expect from Blue, and there was just no comparison for image quality. The lighting hue was wrong, there was a huge amount of pixellation, and it performed as though it was nearly pitch black in the room. I'd say that for the $20 I paid for the unit, it isn't bad, but I bought a webcam. If I wanted a mic only, I would have ordered a snowflake.
Summary: I bought the camera for recording myself play guitar so I can save my song "ideas" onto video. The microphone is supposed to be the same one as the one featured in Blue's USB condenser. I'm not sure if it is, but I record things semi-pro so I can judge a microphone and I would say that this microphone is good if you are recording a sound source within two or three feet of the microphone.
Summary: Blue has such a great reputation for turning out terrific USB microphones that when these units were offered at what appeared to be a great price on an Amazon subsidiary's website, I snapped up two thinking they would be a nice gift for a grandchildren and a not-so-subtle encouragement for them to video chat with me. Unfortunately, these units have been a disappointment, with things getting worse instead of better.
Summary: I bought this Blue Eyeball 2.0 to use for Skype. I have a new, well-equipped MacPro, which I was going to use the Eyeball 2.0 on. I also have a new MacBook Pro which has a built-in iSight camera and microphone. I have high-speed broadband. I had expected the Eyeball 2.0 to be as good or better on the MacPro than the iSight camera and mike on the MacBook Pro. I was very disappointed. The Eyeball 2.0 is a lackluster video performer.
