Self Cleaning Toilet System Replacement Cartridge, 1.65 oz, Lasts Up to 3-5 Months Continuous Toilet Bowl Cleaning - 6 Pack

I've been using NeverScrub! Self-Cleaning Toilet System for several years now, and I'd highly recommend it. Unlike the chlorine pucks that you put into the toilet tank which destroy all of the gaskets in the toilet tank, the chlorine from the NeverScrub NEVER goes into the tank. Instead, the water tube that sends water into the toilet bowl when you flush, runs though the NeverScrub chlorine and delivers it into the toilet bowl while the toilet tank fills with water! Truly a GENIOUS invention! I highly recommend this!!

I have this cleaning system on four toilets in my house. Really keeps the bowl clean, reducing amount of times I have to do that chore. I like the way treated water bypasses tank as this also keeps chemicals from eroding the flapper valves.. Nice product and have been using for probably at least seven years with no ill effects... Recommended.

works good.

This has worked better than any other product I have purchased for cleaning toilet bowls. You will occasionally need to scrub since no product is perfect, but it goes longer between cleanings than alternatives. Easy installation and then you can forget about it for weeks as it does its thing before you need to place a refill in when the crystals are used up. Very light bleach smell but most of the time I do not notice at all. I've been using this for years and have been happy with the performance.

I have used this product for years and it is great! It doesn't turn anything blue, which I appreciate, and my toilets never look dirty because they are disinfected with every flush. The most I have to do is swish the brush around once a week to prevent calcium buildup from our water. It is so simple to install and lasts for months. Yes, it is expensive for something you put in the toilet--BUT not having to scrub toilets is well worth it! I used to be able to buy it at Wal-Mart but now I only find it on Amazon. Yea, Amazon!

I bought 2 neverscrub systems on august 24th 2016. This is the best toilet cleaning system I have used, in fact it is the only system that does what all others claim to do but don't. Easy to install. I stated in my first review not only does it keep the toilet clean, it also rids the toilet of existing stains over time. after using the neverscrub for a week or so skid marks not only form less often, but when they do they self clean themselves, but if the flushing didn't get them all, they will shortly disappear own their own. NO MORE SCRUBBING WITH THE BRUSH

This is a good, quality product that works well.

This product works as well as advertised and in fact for me it seems to last much longer than advertised. Very easy to use (set it and forget it) and it just works. One nit-pick to me is that the odor may be off-putting to some (it does have a mild chemical smell that lingers a minute or two after flushing), but to me its not bad and worth the minor inconvenience considering the job it is doing.
