I recently purchased the compost caddy to go along with our trash/recycling bin from Simplehuman (which we love). The compost caddy is too small to be of much use (this is my own fault for not looking at sizing close enough before purchase), but the bags that are designated to go with the caddy are too small as well - as in, they are difficult to install without ripping them and there is little room to tie them off when the caddy is full. I'm a big fan of Simplehuman products, but I'd look elsewhere for a compost bin if I were to do it again.
