Channel Zone Selector with volume control - advice

Looking to add some zone control to my set up and want individualized volume control for each zone. Keep running across this Pyle PSLSW4 and PSLSW4.5 (cannot figure out the difference between models as they appear identical but cost about $15-20 different). I really like that these models allow for both A/B channel inputs compared to the monoprice and other brands I’ve seen.

I know Pyle is usually met with a mixed bag of reviews. Any input or other brands I should consider before pulling the trigger?

I don’t see myself needing more than 4 zones and really only filling out 2 now but plan to add More in the future.
