Very weak flush for me, toilet unable to flush down all contents. Customer support / the manufacturer did allow me to return this toilet for this reason. They suggested that the poor flush is a result of poor water pressure in my home and this toilet is tankless. My water pressure is adequate so I wouldn’t say the pressure in my home is bad, but it seems this toilet style is best suited for a home with strong water pressure

The toilet itself is great and a reasonable price point. The manufacturer and wayfair were helpful with return.  Everyone else seems to not have an issue so maybe it was a one off
