These Clorox toilet tablets are super convenient and keep the bowl looking fresh with minimal effort. Just drop one in the tank, and it helps fight stains and odors for weeks. Great value at Sam’s Club, especially in the multi-pack. However, be aware that long-term use can wear out your toilet flapper. The chlorine can degrade the rubber, leading to leaks or constant running. I’ve had to replace flappers in more than one toilet after extended use. If you’re okay with doing occasional maintenance in exchange for a cleaner bowl, it’s still a good buy—just something to be prepared for.

Moving to where we did, I didn't expect hard water to even leave toilet rings! After 3+ weeks of using these, there are NO stains whatsoever in the bowl. I have to see if they really last 12 weeks or longer (guessing depending on # of flushes), but super happy I bought them on sale and now a forever fan.

These keep my bowl fresh longer than just brushing. I have very hard water and these aid in keeping the build up at bay.

Eliminates the need to endlessly need to clean your toilets. Yes cheap toilet tank flappers will start leaking at some point with these chlorine bleach tabs. So - you spend the $9 to get the best chlorine-resistant flapper, instead of the $5 cheapie that doesn't last long. They have the good flappers at Ace, Home Depot, etc. No big deal, and no plumber needed! Its easy-peasy to replace toilet tank flappers.

This was the first time I used these. My toilets no longer get a ring just above the water line. I don’t have to scrub every few days.

Works its wonders from the tank, if the bowl doesn’t have the clean smell or generates black spots’ add a new tablet. I’ve found it best to use a quality flapper in the tank.

I have used your Clorox toilet bowl cleaner for many years. Since our economy has raised all prices across the board. I have noticed your discs are smaller, they get smaller quicker and they don't get all the stains out anymore. I still have to use my pumice stone for the hard water stains. We've lived in this home for almost 8 yrs and the last couple years the Clorox toilet bowl cleaners don't clean like they used to. 😑 It's too bad and a lot more work. 😪 Linda from Utah.

It helps to keep the toilet clean and we use this often. However, depending on the type of flapper in the tank, it may cause the rubber to "disintegrate" faster. Clorox claims that if you use the toilet regularly, thereby not having the water in the tank as concentrated, it shouldn't cause damage; but, that's not what the plumber says.

These toilet bowl tablets do clean and freshen the toilet and last 10-14 months. They are expensive, for my budget, but convenient. The only issue of negativity is they cause the flapper to deteriorate and then the water leaks into bowl. This happens in 12 -18 months. Thank you

Worst product I’ve ever tried, the smell of chlorine is so strong it’s impossible to endure. It made me nauseous and have me headaches after only a couple days of having that in my toilet. Worse innovation I’ve ever tried. They didn’t think about how this would smell In a bathroom that doesn’t necessarily have a window open all day long. Do not but this unless you don’t mind a strong smell of chemicals and an even issue with healthy from smelling day all the time
