Easy, inexpensive, and reliable
I'm using the video switcher to capture lectures and classroom sessions when we have 2-4 cameras in use. The switcher is quick, small, and easy to operate. The only downside is that break-before-make (BBM) switching can cause a *blink* between channel transitions, but it is very short and we can accept this given the price of the product and audience for our videos.

Decent, not for high quality usage
This would work when I only had 2 BNC cables going in to it from a hdx900 HD camera. When I plugged in a third input it would scramble that monitor and cause a delay and occasional static in the other two inputs. I tried to see if it was just that input or cable, but it was not. It would only cause this problem when I plugged in ANY third input.
