    Quick delivery, items as described. I’ve 5 of these in my home. One failed (6 yrs old, 2 false alarms in a day) and I needed a replacement. I bought 2, one as a replacement and 1 as a spare. Installed and paired quickly.

    Great product with good price

    Great product with good price, it connects with RING system and it makes updates to check the product and communication is good. Good value, well build and very loud so you can hear it everywhere in your house. Good price not willing to spend over $100 for nest this is much cheaper smarter alternative

    Replaceable batteries, not throw away junk.

    These are nice because you can change the batteries instead of the new models which are one time use and throw away junk that do not even live up to the life span advertised.

    service independent means it won't be "cancelled"

    This does not rely on anyone's external service to work, so use your own zwave hub and it'll last for 10 years!
