Initially interested in this product because it isn’t associated with Alexa or Siri or any other “big brother” listening in the back ground which has prevented us from purchasing other brands. It came neatly packaged. Directions were straight forward. Due to our brick house had to build up a wood platform for the doorbell but no big deal. You can see beautifully from the camera day or night. It allows me to enlarge the picture and I can listen in as well. The camera photo is clear and crisp. I include several photos. The audio is pretty good too. Once it is connected you have to choose the bell chime or it will not chime in the house. You can even set it as an alarm and choose time frame. You can do two way or one way speaking. You can record, screen shot or play back. It allows you the option to sign up with iCloud or use a usb card. The only negative I have is the company could have included some longer screws. I know some users have it a lower rating but I think it is due to user installation error. Overall I give this doorbell five stars and believe it is worth the purchase. I highly recommend the product.
