I'm a retired HVAC technician, and I chose the LG after much research. The feature I was concerned most was the pump cleanout access ,after years of pulling the pump on another name brand. I was a little concerned of noise reviews, but mine is quiet as can be.
Wife and I have needed a water softener for a couple years, so decided on the stacking pair .Wife is 5 feet 2 and reaches controls just fine.
