Absorb Bin Biodegradable Kitchen Fat Trapper - Small 5 "Really useful little pot" Mrs Martin 16 August 2016 I am surprised by so many negative comments. I did buy this when it was on special offer & I have found it excellent but wish I had bought it before. I only came to the page to order some more liners as I have used all I had. Out of curiosity I checked out the previous reviews and I am glad I didn't read them before I bought the absorb bin as I would have missed out out this wonderful, neat solution to a messy problem. I have not noticed a bad smell, but we do keep the lid on unless we are pouring fat/ oil in.
