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

My toilet had stopped flushing every time I pressed the handle, a plumber friend suggested trying these, same day I used the first one my toilet is working properly again. The toilet bowl looks clean and smells fresh. I can’t guarantee how long each one will last, but I’m just glad my flush is working properly again!

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.

works well but unfortunately a block only lasts 3 or 4 days

Brought this product a few times now found them pretty good

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.

Absolute rubbish. The tablets last for three days before they are completely dissolved in a house with two people so don't waste your money!

What's to say? They do the job
