Let me start by saying, I was skeptical about these blue tablets at first. The promise of a self-cleaning toilet sounded too good to be true. But after using KIISIISO's 40-pack for several months, I've got some real tea to spill about whether they live up to the hype.

The good stuff first: These tablets are crazy convenient. Just drop one in your tank and forget about it - no more squeezing messy gels or remembering weekly cleanings. I noticed my toilet stayed noticeably fresher between deep cleans, with that pleasant chemical-clean scent (though fair warning, it's strong initially). The blue tint in the bowl gives nice visual confirmation that it's working.

Now the not-so-great: While they help maintain cleanliness, they're not miracle workers. That 'ring' everyone hates? Still shows up after a few days without brushing. For tough stains (looking at you, hard water deposits), you'll still need elbow grease and traditional cleaners. Also, longevity varies wildly - some tablets lasted me two weeks as advertised, others dissolved in just a few days with frequent flushing.

Pro tip from experience: Always brush your toilet thoroughly BEFORE using these for the first time. They're maintenance cleaners, not heavy-duty stain removers. And maybe don't use them right before guests come over unless you want questions about why your toilet water looks like Windex.

Final verdict? Worth it as a supplement to regular cleaning (especially for the price), but don't throw out your toilet brush just yet.
