This is a good size for my kitchen sink. I also purchased the little plastic bags to go inside. This little pail includes an extra locking clip, as I suppose the one that is there which is removable will break over time. I did notice that I pushed down the lid and it snaps back up without locking sometimes. When this happens I put my finger under the little locking clip from the inside and push up, and that will fix it. It doesn't stay in place so I have to do it pretty often but at least it's still locks. I'm trying to find an ingenious way to keep the lock a little higher on a permanent basis, which I may do with some alien tape which would probably work. The round pail would have taken a little more space in my sink and probably would have been easier to dump the compost in but I like the sleek design of the oval bin. I think the round one would probably take up too much space in my sink although I do not recall the diameter of the round one but that was the deal breaker for me to get this oval one. I do like it and I have to be a little careful when I dump stuff in it so it doesn't go all over the place because of the narrow opening. Easy to clean. The top slips off the bottom by pushing in two little side clips and lifting. Instructions included as well as an extra locking clip in case the one in it breaks. Once they both break then I don't know if there's any replacements but I'll have to cross that bridge when I come to it.
