Fluidmaster 8100 Flush 'n Sparkle Automatic Toilet Bowl Cleaning System with Blue Cartridge, Upgraded Version

I've used many different toilet bowl cleaners in my day, all with very little success. Most might tint the water, keep it a bit more clean, and give it a scent. But this is the first one that actually did the job of regular manual bowl scrubbing. Our main problem is scum/mineral buildup around the water line in the bowl. I compared this directly with 3 different methods to see how well it worked, used in our main floor family toilet.1) Drop-in blue toilet tank cleaner. This did very little to keep the buildup down. Within 2 weeks there was a noticeable line and it needed scrubbed.2) Scrubbing bubbles automatic cleaner. This helped somewhat, but there was still slow buildup and certainly within a month it needed scrubbing.3) Clorox toilet wand gel cleaner. This also did very little to keep the buildup down. Lasted less then two weeks.All of them did decently to keep the water looking clean and a "fresh" scent. However wasn't really what I was looking for.Now the results of this unit... In our heavily used family bathroom - this unit lasted an amazing 3-4 months before it ran out of the cartridge, and the results started to become evident. The whole time it not only kept the water/scent clean, it kept the buildup in the waterline completely gone! I did not have to scrub the toilet once or apply any additional cleaner to it at all. Gone are the days of weekly scrubbing the nasty toilet! This is truly a great product. I hooked this up in line, and in combination with  High Efficiency Toilet Kit - One2Flush Conversion Kit Reduces Water Usage By 40% With Unique Dual Flush System , it connected easily, and it works great. I would definitely recommend the Dual Flush kit, it saves a lot of water.The bleach version of the cartridges work better then these blue ones I think. I also have a septic tank, its aerobic and my final stage treatment before discharge is also chlorine. Still it's best to minimize the amount of bleach put in for the main tank bacteria to survive. However, the very minimal amount this introduces is not a problem (especially when compared to bleach and cleaners from everything else), and its certainly not a problem to my ground at final discharge. Just stating on how I'm not buying into their "biobalance" refill too much.I definitely recommend this product to anyone looking for the best possible toilet bowl cleaner out there. I can only hope the bleach refills go on sale and I can buy them in bulk, because they are a bit pricey when buying for 3 bathrooms every 4 months.

This was advertised as having a month life but it only worked for 2 weeks.

I am glad I've discovered this solution. It makes the World of a difference on the maintenance, dramatically reducing the need to scrub, while keeping the bowl looking sparking clean seemingly indefinitely.

A simple to install, hands-free, scrub-free cleaning system that lasts for 3 months. Exactly what I wanted. Too bad it wasn't even close.It started off on a bad note when I received the kit in the mail (USPS delivers my Amazon packages). Amazon used their minimally cushioned, soft envelopes to ship Fluidmaster's flimsy cardboard packaging for this kit. I ordered 2 sets and both boxes were completely crushed and all the items were loose in the envelope. One of the hoses was pinched and when you opened the pouch containing the cartridges, there were particles that broke off.Installation was simple as promised and after a couple of uses it seemed that it was everything that it claimed. Then, after a week, the blue was gone and this is for a toilet that is used by one adult. Opened up the cartridge and it was completely empty. Our second toilet, used by two adults lasted 2 weeks longer, but still nowhere close to the 3 months it claimed it would last.I figured maybe this was the result of everything being tossed around in the envelope and decided to order the refill cartridges and give it a second chance. Unfortunately, the cartridges come in a similar flimsy box and Amazon shipped it again in the same soft envelope. Of course everything was loose in the envelope and again the results were short of what they claim. It did improve to about three weeks for one and about 6 weeks for the other. And even with the blue lasting longer, it didn't seem to keep the toilet any cleaner. Still had to do a regular scrubbing after about 4 weeks which I thought I wouldn't have to do by purchasing this product.Unfortunately, I haven't been able to find this product anywhere locally because I really would like to see if the product's failure is due to the shipping by Amazon or if it is just a mediocre product from Fluidmaster.

Easy to install, no issues with connection or leaks. Dispenses cleaning agent on every flush.Update: Just to give everyone an idea of how long the refills last. They were installed on May 28 in our main bathroom, which is used by two people daily - it’s now July 11 and the bleach is just running out. The other unit which was installed in the half bathroom which gets about half the use is still running strong.

Por el momento si he notado que cumple con lo prometido, si se instala muy fácilmente, y tal cual, después de cada descarga, suelta el producto para proteger el baño, no suelta el producto directo en el tanque si no en el tubo de desborde de agua, por lo que el producto nunca toca los laterales de la tasa o los conductos donde sale el agua limpia. Eso es lo que no me gusta mucho, no despide mucho olor pero parece que funciona bien, estoy esperando el tiempo para ver qué tanto rinde el cartucho y ver si me animo por otro.Actualización. Cero zarro en el baño! Realmente lo limpia y mantiene limpio. Punto para este artículo.Actualización dos. Me duró 5 meses un cartucho, somos dos personas, pero me parece muy adecuado el rendimiento.

Only just received this and was concerned that it couldn’t be installed or wouldn’t fit in my slimline NZ cistern, but it dors fit and so far works much better than I thought it would. Really easy to install and smells divine! Glad I ordered extra cartridges.

I don't think it lasted for as many flesh is as described. We're also on hard water

My particular cistern doesn't suit this.
