Soft Scrub In-Tank Toilet Cleaner Duo-Cubes, Sapphire Waters, 4 Count

These smell amazing, and work great for keeping the wellwater we have to keep stains away! Great product! I have this on subscription because its that good. Last a long time as well.

I love these! they definitely keep the toilet clean. I haven't scrubbed the inside of the bowl since I moved 5.5 months ago. The bowl is still perfectly white with no spots or film. They do not last as long as advertised, but they're so cheap, I can't even complain. 1 pack/4 cubes lasts around 6 weeks for me. Other than the occasional guest, I'm the only one who uses this toilet. however, I do have IBS and drink a ton of water... so idk, you do that math.

Very strong power and last longer than those expensive once I get at Home Depot. Helps stops the smell and helps clean the toilet bowl.

Works. Great value for the money. Lasts a while.

We have been having issues with mildew rings forming around the toilet bowl in both of our toilets. I expected this to continuously clean and disinfect the bowl with each flush, to prevent these rings from forming. However, the rings still formed, only now they are partially hidden by the very dark blue water created by these tabs. I will not purchase again.They also dissolved quickly (the reason for the dark blue water), and only lasted a couple of weeks.

i can't believe it turn the water so blue i was so happy here i was buying the expensive ones that cost $18.00 dollars a pack make my toilet look like so good looks like i work all day going to buy more to always have on hand i will spread the word give a discount lol

Turns the toilet water blue.

This did not work at all. It never melted in the tank, so the water never turned blue, never got any cleansing. I had to open the lid and get a stick and swirl it around and break up the little block. It didn't do a thing gur the bowl. Still had the same stains. Never had a fresh scent either. Save your money, get a better product like Clorox drop ins.
