bleh

This product is useless. Its faster and cleaner to just pour bleach in the bowl over nite to clean it.
The smell gives me a headache. Its a goopy gel consistency that looks odd plopped in the bowl. It didn't work as good as I had hoped and would not buy this again.

Expected more, bad scent and doesn't do a lot

I was expecting more from this product. To begin with, I felt like a week was a bit of a short time to work, but you'll actually be lucky if you get that much use out of it. We're a smaller household and it lasted just about a week, but a household that flushes more frequently (especially a family with many children) is going to struggle to get even 4 or 5 days. It's quite small and rather than being a neat disc is a weird little stubby star shape that looks like it was plonked there by an icing gun. (Excuse the picture, but thought you'd like to see the size)

The 'spring waterfall' scent is also terrible, it's headache inducing and cloying rather than refreshing like a waterfall. It honestly smells like being smacked in the face with some old flowers repeatedly until you just want it to end. Considering how much I hated the scent, I had really hoped to see a difference in the toilet bowl, but have to say I didn't. Annoyingly, you can't actually clean your bowl properly while this is on, something I hadn't considered, so make sure to clean it before re-applying the next one. But I wouldn't blame you if you just tossed the whole pack in the bin.

One of the other scents might be better, but avoid Spring Waterfall!
