New generation of sensors are great. Same easy installation as previous generation and not nearly as bulky. Crutchfield was same price as the big online retailer with better shipping plus I know I'm getting great customer service with my purchase.

Very Consistent

Richard from Cumberland, MD on 7/29/2020

I got the Home security kit that came with 4 of these sensors and I got to say I love my new system. When a door or window is open I get a notification on my phone plus the base station will put off an audio tone as well. I have a house that was built in the late 30's and I was worried that these won't install very well but must say it was pretty simple to install. Can't go wrong with Ring!!

Pros: always know what is being opened

Cons: Trying to sneak out of the house
