Like many, I've tried lesser expensive, different brands. What a waste. Even now, with money being tight, I'll go it's okay to get a different product because it's on sale, but more often than not, I'll regret it, like why did I buy that? This product makes a horrible cleaning job a snap. Pop the tab in the tank and it does the job for you. When the water is no longer blue. Then, it's time for another. With Clorox, you know it's clean and disinfected.
