I have limited space so this 2 in 1 trash can is the perfect size for a narrow space. I didn't have room for 2 receptacles so my bottles and recyclables were always exposed in a pile next to my old trash can. With this trash can, everything is nicely organized with no one tripping over stuff. I considered the sensor / motion activated ones but decided it really wasn't necessary and would cause me more of a headache changing batteries or being limited to where I place it based on outlets. I am fully capable of using my feet to open the lid; I consider it excercise. The bags can be costly; look for bulk deals [...]. They don't fit as good but you can also use regular talk kitchen bags.
