This is a perfect waste basket!!  It is everything I didn't know I ever needed... and I feel like a magician every time I wave my hand over it and... it opens.  I love the can liner- which keeps the bag hidden and maintains the clean lines of the waste basket.  Even my finicky 22 year old daughter decided she "needs" to have one, although I think SHE will also spend a lot of time "pretending to be a magician" when I can't see her :)  This is battery operated.  The top may stick the first 2 or 3 times you attempt to get it to open but give it a little help the first and maybe second time,and it gets the message and you shouldn't have any more issues with it.  We LOVE it.  However, don't put it in an area where you move a lot because it WILL open when it senses your movement.  Other than that...ENJOY!!
