Amazon BasicsToilet Bowl Cleaners Tablets with Oxygen Bleach, Unscented, Blue, 5 Count, Pack of 1Compact by Design (Amazon-developed Certification)

These Amazon Basics toilet bowl cleaner tablets are a low-maintenance way to keep things fresh between scrubs. Just drop one in the tank and it starts working with every flush, tinting the water blue and helping to prevent buildup and stains. The oxygen bleach formula seems to do a solid job keeping rings and grime at bay without any harsh smells.Each tablet lasts a decent amount of time—I’ve gotten close to a week per tab with regular use—and I haven’t noticed any damage to the toilet parts. They’re especially helpful in shared spaces or high-traffic bathrooms where you want to maintain a clean appearance with minimal effort.It’s not a substitute for deep cleaning, but it definitely cuts down on how often you need to break out the brush. Easy to use, affordable, and effective at keeping the bowl looking clean day to day.

Seems to get used faster then other brands, but still does the job. Ya get what you pay for, etc. etc.

I always feel as if toilets get dirty fast. These things really help with keeping them clean. They are easy to put into the back of the toilet, and they work for longer than I expected. They make the bathroom smell nicer and the toilet looks squeaky clean.

Smells good. Keeps the toilet fresh.. One tab doesn't last a full week under normal Flushing conditions with one person using the toilet.

Simply blue

I love this so much. Keeps the toilet cleaner much longer!

Sadly not keeping the bowl clean, water stains among other things continue. It is truly unscented and the light blue color, well I really do not feel it's effective at all. I'm not expecting perfection but I'm finding myself having to clean just as frequently.

Work great but don’t seem to last long enough. They’re totally gone in a week.
