Not what I expected
I bought these cubes a few weeks ago and was really excited to try them out and see if they actually worked, but I didn't like them. They don't last as long as claimed. They only turn the water blue and have a slight scent, but otherwise, they aren't worth it. It's not something I would buy again.

DO NOT USE
I have been using this product for at least six months. It definitely does NOT help with clogging. In fact, I have to spend the money to have a plumber come out and unclog my toilet. Please do not use this product!!!

The blue gone too soon
I have used these for years this last purchase they both (they come in a pack ) lasted In my husband bathroom 6 days in mine 10 (we moved in a new home) the tanks were brand new. I did notice that the water was bluer than usual since you can’t control how much they dissolve not sure if this is a lot problem from the manufacturer. Will give it another try before I go with a different brand

Not so great featured, and the bowl somewhat clean
Twice I bought this product and in the bowl it did a good/fair cleaning. However, my Home Care person always placed the cubes in the tank. On the second time I watched her to make sure she put these in the right spot. When I looked inside the tank I was shocked 😲 to see the 🔵 blue lining being left on the inside walls of the tank by those.cleaning cubes. I was not happy to see that, which meant half of those cubes were breaking apart and leaving a film behind. I wasn't impressed.

Does not Last Long
I really like this product but the issue is it lasts maybe a week (if I’m lucky) for each cube. Way below what is advertised. This is also usage for two adults. Going to switch to longer lasting alternatives, but for the short-term I like it.

It was ok
[This review was collected as part of a promotion.] The product was ok. I found it went fast. There was a slight color and fragrance. I didn't notice it keeping the bowl cleaner longer but maybe less buildup.

So clean
[This review was collected as part of a promotion.] I absolutely loved it. My toilet stayed clean almost 2 weeks. I don’t have to scrub it or anything. Such a wonderful product.

Not worth the hassle
Don't waste your money. These didn't even last 3 weeks. We have 3 toilets with only 2 people so it's not like the toilets were being flushed and abnormal amount of times. They did nothing for keeping the toilet bowl clean nor keeping a ring from forming. We have hard water which the cubes did nothing for to stop the hard water stains.
