Colpure Toilet Bowl Cleaner， Automatic Bathroom and Tank Cleaning System Toilet Cleaner, Toilet Bowl Cleaner Tablets of Lasts 6 Months or has About 2,000 Flushes -1 Pack (Green)

I purchased this on the 7th, received the 9th and it is the 15th today as I write this review.Started with a clean bowl, inserted the bowling pin shaped cleaner, a very minimal amount of blue appeared - waited the 30 minutes recommended before first flush. Regular use during the week shows very little blue in the water so I doubt it's working as suggested. By this morning, bowl had developed a blackish mold like substance around entire bowl. Does not work - don't waste your money.

The picture/write up states it will last 6 months. Well, they were wrong, it only lasted 1 month. Very expensive for so little time used. I would not buy this again.

I bought this product because it says it lasts four 6 months. The reality is that it lasted only 2 weeks. In the beginning I could see a blue water in the toilet bowl after flushing it but now after 2 weeks it is only regular clear water after flushing. Do not waist your money. I arm sure there is something better out there. If it was not in times of Corona Virus I would take it to the post office and return it, but due to the current situation I am stuck with it.

Horrible. It kept falling over & blocking the stopper so that the tank would never fill & kept the water running.

bought it once worked perfectly for about six months. I bought another one that doesn't work, it only worked on the first day.

First one I seen that lasted for three months

Would not stand up in camode. Blue would not disperse properly.

Great bag!. I took the advice of the post suggesting adding cable ties. Great suggestion!
