Same here. We just bought two and in one of the demo videos I watched it showed them flushing a bucket of golf balls.
Seems golf balls might roll on their own down a waste pipe, turds and paper require water to move them along.
Paying attention to the plumber will cost less in the long run.
They tend to make your sewer line stop up, because you aren’t moving much water through the line. New buildings come with low flow parts in the flush valves. The first thing we do is put parts in to increase water flow. They are good in theory, but ain’t worth a cshit in commercial buildings. I hate unstopping toilets and stopped up sewers. I pay 3.00 for a thousand gallons of water. That means I can flush my toilet at my house 333 times for three bucks, compared to 666 times with a low flow toilet. I doubt if wifey and I flush 6 dollars of water down the toilet in a month. You aren’t really saving much.
But what the hell do I know??
