I have a SimpleHuman compost bucket that I purchased several years ago that I like much better than the new one, which is simply not big enough. I can fill it up in a day or two and sometimes after one meal if I am doing a modest amount of cooking. The compostable liner bags are a nice improvement, as is the plastic inner bucket, which is easy to clean. My older SH compost bin is cylindrical, and has a charcoal filter in the lid to suppress odors, which is a nice feature. Add back the charcoal filter to the new model and make and double or triple the capacity and I'll give it 5 stars.
