NeverScrub! Self Cleaning Toilet System - Automatic Toilet Bowl Cleaner with Starter Cartridge, Lasts Up 3 Months Continuous Cleaning - Refillable Toilet Bowl Cleaner for Stains, Rings, and Odor

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 have tried everything on the market for years now and finally something that works!!!! While my first refill only lasted about 6 weeks I am very happy with the results. I have well water with a lot of iron. My bowl would be stained within days of scrubbing. This is no scrub and I love the clean smell!!!

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 !

I had been wanting to try something like this because many toilet bowl cleaners go directly into the supply tank and tend to either damage the plastic and rubber parts in there, or just keep dissolving (this is particularly a problem for seldom-used toilets. This unit is one that injects cleaner directly into the bowl when flushed so it is only used up during flushes. It also remains out of sight. It was easy to install and looks easy to refill (haven't needed to do this yet). It does not leak as I was careful to tightly assemble the hoses. It also performs its primary duty--helping to clean the bowl. You still have to clean the toilet occasionally but far less than before so it is well worth it in my opinion. The only downside, and hence the 4 stars, is the smell. Your bathroom, especially small ones, will take on a slight indoor-pool scent (the cleaner is probably chlorine based). This actually doesn't bother me too much as that smell makes reminds me of hotels and vacation! It is not a bad scent but it may bother some people. I suppose you could easily counteract it with a Glade unit or similar.

Works great! Way better than tablets, which keep dissolving even when you're gone, and never last as long as the listing says. I have hard water and don't flush every time, and this stuff works. Love that it has no dye. Smell isn't noticeable unless you stick you head in the toilet. Check out the ratings on the refills. People who use this system love it. I'm on that list now.

I had been using the Flush N' Sparkle system for decades but, when the unit started to leak, I could not find a replacement unit so I thought that the manufacturer discontinued it. So, I purchased a Never Scrub unit. It seems to work very well to keep the bowls sanitary between scrubbings but I find that it is really noisy upon flushing. A weird gurgling noise. I just saw that Amazon has Flush N' Sparkle units for sale so I'm going to switch back whin my NS refills run out.

Great product, I have tried the other products and the NeverScrub is the best one. I have 3! Highly recommend!

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.

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.

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

Installed it into my teen son’s toilet because he’s a typical kid who hates cleaning. 2 weeks later the bowl needed a clean regardless. Helps a bit but not a replacement for a toilet brush.

its okay
