Sano Blue Water Toilet Bowl Cleaner Long Lasting Air Freshener WC Tablet Pack of 1

One thing I would urge people to consider is the size of your household. There are only 2 of us and 1 lives here part time. So inevitably this WILL impact on how long this will last. For me it’s lasted absolutely ages and has worked well.I waited until this had run out before reviewing to see how long it lasted, and my goodness it has lasted very long. It only ran out today, rather abruptly though. Last night the water was blue today not. So no warning it’s nearly finished by changing to a paler blue. It cleans well. I’m not sure if it’s supposed to have a fragrance, but I couldn’t discern any and I wasn’t going to stick my head down the pan to sniff the water!I shall be ordering again.

This is second time I’ve bought this and it’s going to be a regular buy now, it takes a few flushes to come through but when it does it’s a really nice, light scent, not thick and clingy like toilet cleaners, and is a clear, icy blue shade that seems to last forever, highly recommend to anyone

Very good ,colour water well, lasted a month,let me know when you make a refill ***

So far this is the best toilet tank cleaner and smell buster I have found. I have used it for over a week and its been great. I would recommend you to try this if you need a bad smell neutraliser.

Excellent once you know the trick to get them working! These last ages, I recommend them but occasionally a new one will seemingly be faulty and won't turn the water blue. You*don't* need to drill into the plastic as some have stated. Simply turn the unit on it's side when fully submerged in the cistern and shake it around a bit whilst also revolving it, keeping it under water all the time! You simply need to get the air block out of the unit as that is why it isn't working. Once you see blue coming out of it, keep it submersed as you stand it upright so you don't let any air into it. This has worked every time for me but you might have to repeat it once or twice before it works. Do this on initial "install" (if necessary) and then you can forget about it till it needs changing months later... They really do last a long time and are totally worth this occasional, minor hassle.

Initially thought it was good but after 2 weeks the upstairs toilet (there’s only 2 people in the house) was decidedly pale blue, the scent seem to disappear quicker than that. As it seemed to be diluting it then didn’t keep the bowl clean either

I have always used some form of blue loo product which over the years seem to need to be replaced far more often than stated by the manufacturers, but not in this case.I was very surprised to find that mine has been in the cistern for over a month now and it is still going strong.I do use the subscribe and save feature (monthly) on here so as my new one is due today I thought I would pull the old one out just to see how much had been used and ....... well now I have a blue bathroom floor and very blue hands, so I don't advise trying to do that yourself.Very pleased with the value of the product and I can highly recommend it is you want a loo block that lasts a long time and is great value.

Not compatible with standard size cistern as too big so gets stuck and toilet doesn't flush properly
