Good value and function perfectly as door stops - but by golly these things really stink! OK when in use and on the floor in a well-ventilated room, but I used one of them and put the other two in a drawer for later use - when I next opened the drawer the smell hit me like a hammer and almost made me gag, so I triple wrapped them in cling film and put them in the garden shed. I can't imagine why they have to smell so bad - presumably they are made out of recycled materials - I dread to think what!
