Shape is what it’s all about.
I absolutely love it. I only gave it a three because it is very noisy and while it is 14 gallons it seems the ones where the kids pop up and down hold more. The sensor on the sliding seems to be way more sensitive then the up and down model. I love it because it fits right in between my stove and counters. This is my third one. The other two were the up and down style and I seem to break the lids easily and it’s more cost effective to purchase a whole new one. I put the bins out on the patio of the broken models. Works for me.
