After a horrible experience with the Ring doorbell recommended by an electrician (darned thing demanded CONSTANT maintenance!) my daughter recommended this simple system. The button outside contains a small battery guaranteed for three years. The inside chime simply plugs into an outlet and you are done! No constant recharging, no adjusting camera settings, no logging on, no constant resetting to reestablish the link. It’s a no frills door bell that actually works! Frankly it’s hard to understand the complaints of some reviewers about the selection of ring tones. With over 50 to choose from they were still dissatisfied? I am absolutely delighted with this purchase!
