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

works good.

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.

This is a good, quality product that works well.

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!

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.

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

I love this product because it works really well. I just wish it wasn’t so expensive! That’s why I’m only giving it three stars for value for the money. The problem is… There isn’t anything else like it so if you want some thing like this, you have to pay that money.
