Duzzit Power Bleach Toilet Block White, Loo Deodoriser, Cistern Block, Bleach Block x 6 (2 Pack Bundle By FREYPAC®, 12 Blocks Total) (White)

I'm no expert, but these tablets seem to work ok. Just drop one into the cistern and let it do its job. The instructions are a bit out of date. "Gently drop into the cistern, the other side to where the handle is situated". Mine doesn't have a handle, it has press buttons in the middle, and there is no indication as to how lo0ng a tablet will keep working, so that's down to guesswork, but it does keep the bowl looking clean, and that's the main thing.

Nice bleach blocks but no bleach odour and no foam when used. Have tried better. Will stick to the blue ones rather than these bleach type.

A week/few days less long lasting than more expensive brands but performance is the same.

These do the job fine, but only last for 5 to 7 days!!! I live alone so its not like the loo is getting an excess of flushing. It's a good job you get 12 in the 2 packs.

I couldn’t smell the bleach

Bought these cistern blocks as an alternative to bloo blocks, less than half the price and lasted as long if not longer. Cleans the toilet well with a nice amount of foam. Brilliant value and will definitely purchase again.

I bought these expecting at least some sort of bleach clean smell after flushing…..there is absolutely no fragrance at all after flushing so not sure that any bleach is being released.

OK but doesn't last long... Froths up nicely in the lou... And fresh bleachy smell..
