The first product I received was actually defective due to the sensor not working, but if you notice, I still gave this product 5 stars. Their return policy had a new can on my doorstep within a week and works flawlessly! The sensor isn't too sensitive where it's opening every time you walk by, it just works as expected. Walk up to it or wave your hand and it will open for you and stay open until you walk away. "Open can" and "Close can" voice prompts work about 95% of the time, which I'd say is pretty great! Fits perfectly in my kitchen and looks great!
