I have used this for 4 weeks now....I am so pleased with this product! The black stuff has NOT appeared in these 4 weeks, there was a little bit of "brown stuff" after 4 weeks and I used comet and a brush to clean and it took literally 15 seconds and zero scrubbing, just swishing to clean the bowl. Love this product and have been talking "Cleaning Toilets" with my friends 😂! I have sent them to this sight - they know if I recommend a product you can take it to the bank that it works! Thanks Krazy Klean! I sure hope it keeps working!
So I saw the ad online and I just had to buy it. This product was literally the answer to my prayers. I HATE cleaning toilets. One month later and I have not cleaned the inside of my toilet. This product works very well.
I thought I d give this a try, so far it’s been 25 days and I haven’t had to clean yet, impressed so far!!
I’ve used these for over a month now, after a nasty bout of norovirus struck our whole household and I spent hours up-close-and-personal with my toilet.
I can definitely say that these work well! We live in Pittsburgh and have hard water, and these have kept the grime line out of the toilets since day 1.
Highly recommend!
