Put the unit in all 3 of our toilets and they have been stating amazingly clean since.
I got this 4 months ago and it does clean only one problem the area where the holes are below rim where the water comes out does not clean, some darkness, had to hand scrub that area.
Things do not cling to the bowl as much, and no hard water ring, but still necessary to use toilet bowl cleaner every week to get under the rim real well. I can live with that.
I’m always hesitant to purchase anything these days because of scammers. I love this product and it works as promised
this product WORKS. I believe 100% of what is advertised. The scrubing is gone. Now it's just sanitizing the toilet. whipping down the extreerior.
The tank is cleaner.
