Completely thrilled, over bad smells in the bathroom! hermetically sealed, the system is very well designed. Nothing happens. The use of ordinary bags motivated my purchase, it's great! No extra costs, which is not négilgeable. Easy to use, my 18 month old son put himself his diaper in the trash and operates the rotary handle, loves :) Attention provided to layers only. Forget petis cotton and cotton swabs, it gets stuck to the mechanism. The capacity is 15 to 20 layers, depending on the child's size (and the contents of the layer;)) I vacuum once a week. Apnea is recommended at this time;)
