Works great and lasts a long time. I bought it to keep mold and mildew down between cleaning. GREAT! I would not recommend if you have pets, because you can smell the chlorine when you flush.

Works great! All bathrooms do smell like chlorine but toilets are spotless.

A lot smaller than the major brand. They work just fine, but not for as long.

Keeps mold away during the hot months. The bleach smell is a bit too much, though. So, I'm going to try and half them next time I place them in the tank

I buy these regularly and they actually work really good. I tried the Clorox bleach and blue and that was a complete disaster. These white tablets are bleach they smell good and they do a great job cleaning your toilet and the inside of your tank reservoir. Highly recommend. A++

These do work at keeping the bacteria away, but they don't last anywhere near 30 days. And they smell about 10x stronger than the standard Clorox ones. Like the other reviews say, these are almost overpowering in a half bath.I was trying these to see if I could find something cheaper than the Clorox ones. These are cheaper but you'd need 2 to last a month and the smell is kind of unpleasant. I'm fine with trying them out but when the last couple are gone I'll go back to the Clorox tablets from Sam's club.

Does clean well, but sometimes has a strong Clorox smell.

The good:1. effective at reducing stains in the toilet bowl2. very easy to useThe not so good list:1. As others have mentioned, the tablets tend to dissolve pretty quickly and often produce a floating, fluffy, white residue that stays in the toilet bowl after flushing. It sort of looks like remnants of an almost-dissolved bit of toilet paper. Nothing bad about it, but it's not that clean toilet bowl you might have expected.2. When the tablets dissolve in the tank they release chlorine gas. It turns out my toilet flushing mechanism -- the Kohler cannister flush valve -- has a lot of components that don't like excess chlorine. In the past year I have had to:- replace the large sealing o-ring at the cannister base when it developed bubbles in the rubber, causing the tank to drain steadily into the bowl, and the tank to periodically refill,- replace the plastic tube providing bowl-fill water as the tank refilled. The tube became brittle because of the chlorine, cracked, and failed so that there was no bowl refill,- replace the metal flush lever after the chlorine gas corroded the shaft on the flush lever such that it would no longer turn in the plastic mounting sleeveIf your flush valve and refill mechanisms are impervious to chlorine, go for it. If not, you're about to be in the toilet maintenance business.
