I had never dreamed of spending this much money on a webcam before, but I was getting fed up of low quality images. All I can say is you certainly see difference spending a bit more has made. This product was very easy to set up, the picture quality is out of this world.
Initially I did experience some background noise and echoing from the mic but as I filled up my office I realised this my fault, as my room was bare and this was just due to the simple laws of physics; because the bare walls reflect the sound waves rather than the fabrics and carpets absorbing them. Once my room was setup correctly I noticed that the mic doesn't pick up back ground noise.
The autofocus works really well and this product is well worth 5 stars. If you are looking for a decent webcam then look no further.
