More detailed review below. HardwareFirst off, this device is sleek, nice looking, and ROCK SOLID. The connectivity and wireless range on it is great when compared to previous and competitor models. I did not feel worried about breaking it during install because when you hold the device you can tell it is manufactured well with durable materials. In the past, all other doorbells to this point felt dinky and plastic not to mention that most were ugly. As for the WiFi connection, this works great. You will need to use a 2. 4Ghz WiFi which makes total sense because the signal has to get through exterior walls to the doorbell 5Ghz doesn’t travel as far or through walls as well. I originally had issues with connectivity but this was resolved when I changed my own set up a bit. The device glows a nice LED color right on the button itself and on the top. For those of you who love to change the look of things, this LED color is fully customizable via the SkyBell HD app so the kiddos in the family like to make it match the current holiday!Picture/Audio QualityThe picture and audio quality on this device far surpasses anything else I have used/tested.
