Loving it - Thoroughly clean without damage to my septic tank

So far, so wonderful! They leave a thorough clean flush, smell good and so far haven't caused any septic tank blocks .... looking forward to many years of happy septic tanks and fragrant toilets. My drains; which have been consistently blocked, now appear to be running clear. So all good on the homefront and I plan to continue to order this product regularly.

So Impressed

I'm now ordering these in bulk, because I'm so impressed with them. I ordered one to try, initially, and noticed that it said it helps to keep drains unblocked, on the wrapper. We have endless issues with our drains, and regularly have to have them unblocked. I mentioned to my dad that these cistern blocks could help with this. A few days ago he came to me and said that he could see there was a difference...something was keeping the drains clear! So here I am, now ordering the bulk pack, so that all 3 of the toilets in our house can contribute to unblocking the drains!! Your products are exceptionally effective.
