20 Pack Toilet Bowl Cleaner Tablets,Blue Automatic Toilet Tank Cleaners, Long-Lasting Household Toilet Cleaners,Toilet flush Cleaning & Deodorizer

We have well water, it is hard. I use these to keep the buildup in the toilets from accumulating. Drop one in the tank every few weeks and forget about it. I love the fact that i can get 20 at a time, and shipped to my door. Smells great and keeps the toilet clean between cleanings.

Doesn't last long. 1-3 days

it did make the toilet water blue and looks nice. It covered water color perfectly. However, it doesn't last very long, of course it depends on how many flash use, but it was just me the most to use. It will stain a little on your hand when you do the new one, but it's washable.

Waste of money. Each tablet last at the most 4 days , we have 2 toilets for only two people , got this product on Dec 31 it’s Jan 8 already used 3 in each toilet , they accomplished nothing except make the water a pretty blue for a couple of days, no cleaning no deodorizing zero effect. I’m so tempted to return the remaining ones a demand my money back but as a family of 28 within 10 miles I feel word of mouth will be more effective. Don’t buy!

These work excellent and I barely have to clean my toilet bowls anymore. Some people complain about it smelling too much like bleach, but I think a sanitized smell in the bathroom is a good thing. The smell is not bad and usually only when you first put the tablet in the tank. The tablets last about two weeks and you need to make sure you put a new one in when the previous one has completely dissolved. I highly recommend this!

Did not last longer than 3 days. Was effective keeping Bowl clean.

I have just started using these, but they seem to be doing their job quite well. I cannot speak for durability yet, but the color is just right for us. Not too deep of a blue, but a great shade of blue, as seen in the attached pictures. The price is quite resonable, which is great as we have 4 bathrooms. It is also good that the individual wrapping is water-soluable, therefore, it does not need to be removed for disposal, and no personal contact with the chemicals. We are placing these in the hang-on-back Tank Caddy, which we also purchased from Amazon. It seems to be a great combination! Overall, it seems to be a great product.

Works just okay for the price. Doesn’t last the advertised time. I probably won’t buy again.
