Definitely...the reason that those caught my attention is that while we have a wealth of MONO submixers, the amount of STEREO submixers is pretty skimpy at present. Not only do these do that on a massive scale, they're inexpensive and super-simple. Now that's value! Plus, if you want to hard-pan signals to the left or right, you can do that for four stereo signals with the same module, and even have some panning "leeway" by careful adjustments of the input levels.
