I’ve only had mine for a few months and while it has in fact delayed cleaning more often than usual, you do still have to clean! It makes cleaning faster and easier though. Still love it so far and hopefully it truly lasts ten years. I have boughten more since first purchase :)
Since using this product I have had no toilet ring from my hard water! My toilets have never been this clean! I am amazed that these work exactly as advertised!
We tried everything to keep the water stains out. This product works!! I highly recommend this!
