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

I agree with other customers that this product lasts about a week in the cistern , however I needed it to clean the mould out and it did this job fine. It does foam in the bowl.

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.

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 The instructions are a bit out of date.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.

It foams really well and seems to activate quickly after immersion in the water. No detectable fragrance, but leaves loo looking cleaned and sanitised…. BUT IT DOESN’T LAST LONG AT ALL! Say 10-15 flushes per block, about 3-5days use?! Overall, still cheaper than the branded ones coz you get enough blocks to make it worthwhile, so will likely buy again I think…maybe…perhaps. 😂

Cistern bleach blocks are thin on the ground so I get these from time to time and they're ok in that for a couple of days they foam pleasingly with the flush, but then they peter out. They certainly don't last a week. I can't say that they really work but I expect they do something subtle. I mostly pop a tablet in the cistern when people are coming over. Day to day it's not worth it.

All good does job perfectly. 👍

a few flushes and it dissoved to nothing .will try another product or just carry on with bottle bleach.

Brought this product a few times now found them pretty good
