    Quality smoke detector but difficult to install

    This smoke detector seems to be of good quality but it was difficult to install. The installation should be more intuitive. I rarely have to make a call to do an installation but with this it was necessary. A second install would be easier but that is little solace. I am on the fence as to whether I would recommend this.

    I really would have loved if this was wired. The ones in my home are currently wired so this did not work for me. Ring needs a wired version.. I guess their fix to add to your current system is the listener. .. I rather an actual alarm.. This went back..

    The product by itself works just fine. The pairing with Alexa though was a nightmare. After a few tries I gave up and basically using it as a standard smoke and CO2 alarm.

    Very difficult to pair. It took several tries to add this to my Z-wave network. Probably the most trouble I've had with a device so far

    You need Ring Base security system for this to work. It will not work with stand-alone Ring system, Google home, NEST, ADT, etc.

    I purchased 8 of these and they are absolutely terrible!! I’m always having to replace batteries in them . Received 1 and it was already messed up and wouldn’t work . To bad I opened them up after the 30 day return pilot I would have returned them all !! I paid over $360.00 for them and regret it every day ☹️

    Works well. Doesn't connect to ring like I thought it would, but a solid unit none the less.
