I don't know about you, but I don't like to open my kitchen garbage can with my hands.
Not that it is dirty, but when you have trash in your hands it is hard to do that with one hand.
What I like about this product is that its is motion-activated, stainless steel and has very long battery life.
Anyone who does a lot of cooking or cutting up veggies know what I am talking about.
I had a look at several models and brands. This one I found had the highest customer ratings on Amazon.
Most of the time this is something you can count on.
