Great quality
Easy to install. Very durable. Wireless range is top notch. It’s loud and has multiple volume options. Lights up in the night. Works great even outside.

Has lasted 3 years now
This thing has survived storms and intense heat being outside all day. I think I’ve only had to change the battery once in a year. It looks great, like any simple doorbell.Plenty loud and great how you’re able to plug it in anywhere you need to. Works great. Super easy to get set up, just plug it in and follow instructions to connect.The stick on to mount it has lasted through rain or shine. Couldn’t be happier with the product and the price.

Exactly what I wanted.
Easy peasy. Received about 2 hours ago. Ten minutes to set up right out of the box. Instructions were plain and easy to follow. No problems at all. So many rings to choose from. Most of the setup time was spent deciding which ring we wanted. We decided to choose one and try it for several days. It's very easy to change the tone.
