Not sure how I lived without one before but I will never go without one again. Both of my cats took to it within a week so the old box was gone for good. Make sure you set the child lock even if you don't have little ones in the house!! One of my cats while sitting on top of the genie turned the cat activation off and I did not discover this for a week, oh my what a mess. No more troubles after i turned the child lock on though.
