This is my third motion sensor retracting trashcan. I like the height, that I do not have to bend down and I like it that the top retracts so it doesn't interfere with anything about it. It does a good job of containing smell also. I opt to use the AC adapter instead of batteries because it becomes an alluring toy for anyone who hasn't experienced a sensor of this nature before and that wears the batteries down. There is a switch on the back which you can turn off to leave it in the open or closed position.
