I bought this trash renewal of another (of Open'up mark) that was not working. I am very happy with this new bin: it works perfectly well; I read in a comment that the opening could be time to fire, which is not the case at all. My previous trash was 30L, this one is 50L: I hesitated to take this capability, because it takes a lot of space, especially in height, but thanks to its particular shape, this one does not take more space than 30L in height, but is a little wider. The fact that there is no tray is not a problem: the bag holds up well around the headband, but I advise to take bags with elastic. I also read that a hygiene point of view it was embarrassing: I do not think ... anyway, whether or not in a bin, the bin stays inside. In addition, small but insignificant detail which one does not think: there are slots on the lid that open the trash manually if pils are down or that the trash is off. Allow 4 LR20D batteries
