Great for normal use, not good for fast switching

I was hoping to use this device to quickly switch between multiple cameras and a microscope video feed to avoid needing more than one HDMI capture card on my computer (for use making instructional videos). The problem with this is that it takes about 5 seconds for this device to switch between inputs, during which you just get blank video output. This is certainly fine if you are using this a more typical way where a 5 second delay doesn't matter, but it is definitely not ideal if you are wanting instant cutover.
A couple more caveats that might affect your use of this product: it does not have any holes or brackets for mounting, and the output port is on the side of the device while all the inputs are on the back--This can make cable management awkward if you have limited space to place it.
