Never Scrub Automatic Toilet Cleaning System - New/Improved by Never Scrub

The previous toilet bowl stains disappeared and the bowl is staying white and clear of any hard water stains. Smells fresh, a bit like a hot tub as it likely uses similar chemicals. Should be good for 3 months so just need to find a good place to shop for the refills now.

I purchased another brand of a similar system and wasn't completely satisfied with it, but at the time, it was being used on older toilets. We replaced all of the toilets in our house with new Kohler toilets and decided to try this brand, and I am very pleasantly surprised at how well it works. Basically, I have not had to scrub my toilet bowls now for 4 months at all.

You either have to buy new plastic inserts everytime or a whole new device.

I bought both this and a similar product by KSend which is about 66% cheaper. So I'll do this in more of a comparison review. Value: - The KSend is cheaper at about $10 and uses standard toilet bleach generic pellets. - The NeverScrub! uses their refill cartridges that are filled with bleach granules, the refill cartridges are around ~$5 each and are supposed to last up to 90 days -- however the cartridges are easily disassembled, and you could likely break up some generic pellets to refill. Quality/Construction: - The KSend is Made in China and the plastic feels noticeably more flimsy. You have to really screw down the cap or higher pressure water systems will cause it to leak. - The NeverScrub! is Made in USA and the plastic feels more reinforced/rugged. You also need to make sure to secure the top as needed. It also doesn't hurt to put some hose clamps on if you have high pressure in your water lines. Function: - The KSend pushes water through the housing and then directly out the other side into the outlet tube, because of this wide-open design you tend to get a powerful smell of bleach in the toilet, and the bowl water is noticeably "yellowish" from the bleach being in the water. - The NeverScrub! uses a more restricted path with the water flowing in the bottom, getting pushed through the bleach granules, and then back out into the area where it leaves the housing. I didn't notice any strong smell and it seems apparent that there's not as much bleach being dispensed with this design (a good thing). - Both seemed to keep the bleach from getting in the upper basin assuming they're properly secured and installed. Conclusion: Given the fact the NeverScrub! design seems to meter the bleach better and feels like it's built to last longer overall, I'd have to recommend going with that design -- I relegated the KSend to the guest bathroom just because of the strong odor. The downside of the proprietary refill cartridges is mitigated by the fact the cartridges are easily refilled with very little DIY.

I really tried to make this work. I had bought 2 of them. Water sprays out of a casting pin hole and shoots straight up. The defect was in both of these units. I dried off the first one and sealed the pin hole with silicone. After it cured and I reinstalled it both fittings (not the tubing) on the inlet side was spraying the bleach water into the toilet tank and because of that the bowl level was not even close to the normal level. So I took it out again, dried it off and siliconed both fitting leaks which I shouldn't need to have to do on a new unit. Finally now no leaks! The next issue is when you flush by the time it gets the air out of the system it shorts the water to the toilet bowl causing a low level water level in the toilet bowl. There was also several plastic shavings inside the bodies of both units when I received them. I think the idea is great however the quality of manufacture is at a very low level. I never installed or used the second one because of such poor quality. I will try the Fluidmaster brand and hopefully it will be better. YOU SHOULD ALSO BE AWARE THAT THESE ARE NOT RETUNABLE !
