These toilet bowl tabs are great (if you don't mind using bleach... I know some people are weird about that). They seriously last 4-6 weeks in the tank and keep the bowl sparkling clean. You still have to clean the bowl occasionally but they keep hard water from staining your bowl and there is no nasty build up under the rim! Sam's Club is one of the only places I can find these tablets and I HOPE they keep them in stock because they are totally awesome! Even turned my daughter on to them because she asked how I keep my toilets from staining... these bleach tabs are the answer!!!

This toilet bowel cleaner keeps the hard water in my area from making a line around the bowl. It took me a little while to get used to the Clorox smell when I first put them in my tank, but the smell is something that I think you would get used to. They keep my toilets looking pristine!

I've been using Clorox Bleach tablets in my toilet tank for over 30 years and love this product. I clean my toilet at least once a week and these tablets prevent black mildew stains from accumulating just under the rim of the toilet bowl where the water rushes down to flush. It's an area that my toilet brush can't reach. I only have to drop one of these tablets into the toilet tank every 1 to 2 months. I highly recommend it!

If you are a neat freak like me, this is your stuff for that stubborn, nasty looking lime ring build up on your toilet bowl.. This stuff works to keep your toilet bowls immaculately white!… I have 4 bathrooms, all have white or white-based marble and granite.. any speck of dirt drives me nuts, this stuff has kept me sane without the trouble of scrubbing our toilet bowls like crazy.. It literally cleans your toilet bowl every single flush leaving nothing but Clean and germ-free toilet thrones!

I have used this type product for many years. Works great for keeping the bowl clean and odor free between cleanings. The tablets also solves another issue; they keep the tank clean and odor free. No more mold in the tank or bowl! Great product Clorox!

We have always used Clorox Automatic Toilet Bowl Cleaner. What we love about this is the fact that we don't have to clean the toilet bowl that often. The tablets take care of that. For busy people like us, this is great. Sparkling bowl for less work.

These work great. Where I live we have really bad water and so if we don't use this product I grow mold in my toilets. Nothing worse than looking down into the toilet as you're getting ready to sit down on it and realizing there's mold growing inside the toilet under the water. These tablets help stop that. In fact that's how I know when I need to add a new one is that the mold starts growing in my toilet again. I highly recommend these. At first it it smells a little like chlorine but then I no longer notice the smell.

I have had no problems with this product when buying from in store but I ordered these and had them shipped. The first one I opened was broken in three or four pieces. The next one was okay. So I just hope the other four are okay when I need them. I really like the product and it does what it says it will do, but when one is broken you have to throw it away and they average out over $2 apiece with tax.

I love these discs, keep my bathrooms smelling fresh. I haven't experienced the issue where it corroded my inner plumbing workings, but will cross that bridge when I get to it. I like how it eliminates the ring in the basin and emits a fresh chlorine scent well after many flushes.

I love these things; they keep the toilet looking better between cleans. However, if you purchase them anywhere else, you are paying WAY too much for them. I have price compared, and while it seems really expensive, you are better off getting these here in the long run.
