Automatic Toilet Bowl Cleaner, Lasts Up to 300 Flushes, Deodorizes and Fights Hard Water Stains, Safe for Septic Tanks

Easy to install and keeps the bowl clean. Doesn’t have the strong chemical smell or artificial dark blue coloring that stains the bowl like other toilet cleaners. The price is worth the quality - it’s a soft blue with an elegant fragrance (floral citrus). I bought one to try and loved it so much I purchased more for all three bathrooms in my house :)

The product, while unique in its design approach, is unusable. The product could not be hung from the inside of the toilet bowl as the arm does not extend enough to hang. Further, after taking the seal off, the diffuser assembly fell out and of course all of the contents that are meant to dispense over time practically came out. Overall not a durable product and not worth the value for you money.

Works great! Easy to install. Keeps toilet fresh!

Got this on time, and so far very happy with it. Definitely watch the video just make sure that it's not mounted too high so when you flush the toilet all of the solution doesn't run out too quickly

We have a variable flush toilet (water conserving) this failed miserably. Didn’t last long either. Needed to adjust it every couple days. Can’t recommend.

Installed 2 in a couple of tanks 3 weeks ago, I'm using them in conjunction w/Clorox clinging gel once every few weeks and don't see that the Happy Tank does anything but die the water blue. The tank and bowl still get dirty below the waterline, where at least the gel helps under the rim and sides of the bowl for a few days. I'm switching to Clorox tabs.

The media could not be loaded. Great for easy cleaning of your toilet. As long as you wipe out your toilet a little bit before you install it, each flush of the device helps keep your toilet super clean. I like the fragrance and I like that fact that it’s automatic.

It worked but lasted less than 3 weeks. There are only 2 of us and I’m gone during the day; I would expect it to last longer. I also did not like that my toilet lid would not set level, due to the bottle hangs from the top of the tank.
