The diaper pail works with a simple principle. An endless bag, a collecting area and a rebounding flap. However, the specified storage space with 46 diapers is the most optimal best case. Realistically, I'd say between 35-40 diapers you get pure in every case. From the smell of the bucket is truly amazing tight. Here I want to say anything negative! The only thing that bothers me a little bit in this system, is the somewhat high price of refill cartridges. Actually one should think that these cartridges are a little cheaper. Here you have to take really the follow-up costs under the microscope! Therefore, there is the bottom line a star deduction!
