works and sticks - tip - clean toilet first, let dry then apply, first one might be a bit dodgy to come out but rest easy as and good. i like lime zest - toilet used lots per day and 1x gell lasted about 9 days, nice clean fresh smell, toilet still flushes well - will keep using - been hot here - 36oc outside but still stuck, but home is cool inside so maybe heat not hot enough to soft? will see over summer. i have chemical sinus problems but this does not affect it

Seems impossible to even apply, all sticky and not firm coming out when trying to apply but falling into pieces and not wanting to stick to the bowl. Had to grab the gooey mess off with my fingers and press but very dubious it will hold at all if I flush, not happy

Like most people here my duck discs also met a very early final flush! 72 hours in fact was the total time these discs stayed in place. But then Brisbane has a hot day and these things just liquefy and slide right off the loo bowl!! I'll bit be purchasing these again as the are really expensive for the use... About $1 a day when you think about it!!

I love the of a non-cagey concept but since using these I almost immediately get a headache after going to the loo because the smell is simply too strong, like the kind of strength you'd put in the locker rooms of footy players. I once halved the size of the disc by scrapping some of it off with a disposable knife and it still smelled too strong.
Easy, it sticks well, you don't need to scrub the bowl everyday because there's no yukky loo water smell.
The SMELL is too strong oh my GAWD SO strong!!!

Great product in theory, but Not in realty, not a good product waste of money, the toilet Duck it cost $10 when on special and washed away within the first one to two flushes of the toilet, total waste of money, I would not recommend this product to any of my friends or family.
Nothing.
Didn't stay stuck to the bowel, flushed away within first few flushes.

I signed up just to review this awful product. I purchased original scent and within half an hour of using them our home smelled like a cheap pub urinal and we were coughing and wheezing. And we don't suffer from allergies or asthma usually.

Horrible, nasty fragrance, astringent and bleach-smelling. Overpowered the entire house. They were removed immediately and we've chucked the rest of the pack out. What a waste of money.
I liked the concept because I hate cage (nasty Gerry things).
The smell.

I really like the idea but they just don't seem to stay on the bowl, they slide off. A complete waste of money and I'm really disappoint. Doesn't matter where I stick it on the bowl it just doesn't want to stay. I think it needed more work before it was put on the shelves!
Convenient (if worked), pretty looking
Useless, doesn't last up to 7 weeks as claims. I'm lucky if I get a few days out of one.

Clever idea, disappointing execution. These things smell *awful*. So bad. It's a nasty, cheap, chemical fragrance - just like what you'd expect to find in a poorly maintained public loo. The fragrance spreads throughout the house, and will make you feel ill. What ever happened to subtle, natural fragrances with real natural ingredients? I threw mine out after a day. What a waste of money.
Clever concept. Like the idea of no plastic cage.
Overpowering, cheap, nasty, chemical fragrance

I love these discs. I think they look really pretty on the bowl and they fill the bathroom with a nice smell after each flush. They seem to keep the toilet cleaner as well. I have never had an issue with them falling sliding off the bowl and they last about a week. I wish they came in some more fragrances and colours. Perhaps a pink pot-pouri or rose or an orange peach fragrance.
The smell and it keeps the bowl clean.
Goes a bit "gooey" after a while.

Awful! Smells like there's a smoker in the house. Why can't we get refills for the other scents. The lime is dreadful. Get Rid Of It! I've chucked it out. I love the product and have been using the other scents, but the Lime is really awful. Please make the other 2 scents available as refills.
Nothing at all other than the fact that it was available as a refill
Dreadful odour/perfume!

I had to the scrape the stuff off the toilet bowl after only a couple of hours. The smell was overpowering!! Made my entire house smell like a toilet. Will not be buying again. Also the smell was meant to be "lime" so I was expecting a nice citrus-y smell and it smelt nothing like lime.

Smell was awful and far too strong

The idea is good, in that its more hygienic and smells pleasant, keeps the toilet clean. It doesn't last very long though. It becomes a blob of goo after a couple of days, even when in a position in the toilet bowl that doesn't get much water during a flush. I don't think its worth the money.
Hygienic
Doesn't last as long as its advertised to

I've used this product in two houses now and both times had no problem with the discs sliding off - must be the type of porcelain?

When the disc gets a bit old, I just get the toilet brush onto it and do a good toilet scrub before re-applying another disc.
Hated touching the cages!
You cannot buy refills by themselves - must keep continually purchasing a handle (even with the "refill" packs) - environmental and financial waste.

I found this product to be very pleasant smelling & easy to use, it's a great idea but I found it slides down the side of the bowl during hot weather after a couple of days. Not sure if it's the process of application or not but it performs differently depending on weather conditions. I wouldn't recommend it for families with small children as it would become a novelty for the little ones, but, it's very convenient.
Pleasant smelling & efficient
Doesn't perform as promised

Having applied the discs in two toilets, I was pleased with the way they worked and the fragrance was pleasant. But, after a few uses, they started to slide down the side of the bowl and within a few days were gone! I re-applied and have had the same result - not happy!
Smells nice, works well for a day or two.
Doesn't last.
