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

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.

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!

Only 4 stars as they don’t last long .but they do the trick

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. 😂

Have been using this for approximately 6 to 9 months and don’t know how I managed without them ,they keep the toilet bowl lovely and clean and smelling fresh , I put one into the cistern every 4 to 5 days for a family of two saves all that scrubbing. Recommend them to everyone makes live easy and seeing I have osteoarthritis in my hands just what I needed

These are not worth buying. They lasted two days in my cistern. There’s only two in my household. They are rubbish.

Good but not long-lasting. You will have to buy loads if you use this.

Very good
