Very skeptical but am now a believer. Almost a month of using and the bowl is still clean.
so far this product works. keeps the bowl clear of rust stains. have been using for about a month, 119 months to go.
I lived my whole life thinking the ring was poop. I literally tossed this filter in our tank and have not seen a ring in over 2 months. Obviously, still have to disenfect the bathroom like usual but I used to see a ring every week. Seeing and believing are 2 different things! I love never having to see a ring ! I got one for my mom, sister SIL and MIL. They all love and see too! Thanks for fixing a problem i didn’t know could be fixed.
Since using the pumice stone, my toilets are miraculously white! I’ll admit, I was skeptical…but hallelujah, they look like brand new! Thank you ever so much! And Happy New Year!
