So far this is the best out of at least 8 different styles we have tried. I like the open top.  After trying various flip lids, this open top works best for our family.  The trash does not smell nor can you really see any trash unless it's at the brim. We somehow lost the plastic ring that holds the bag on before the cover is placed on.  It still works without the holding ring.  Like the streamlined look. One side is flat to fit up against the wall, which takes up less room than an oval or cylindrical can.
