    Will never buy these again. I can not get these to reconnect to my wifi after I upgraded my system. It will no longer connect to any of my smart home systems that it was originally compatible with. I have to login to my phone to turn on the lights or adjust the settings. Definitely not doing the job I purchased them for.

      We are sorry to hear that! Our lights and plugs require a 2.4ghz wifi network to connect and use. These devices will not connect to 5g networks and if you have a mesh blended network then you will need to disable 5g momentarily to connect and then re-enable 5g. Feel free to reach out at 1-844-302-2943 if you need assistance with this. -Cync Support Team

    I love these light bulbs! You can change them to whatever color you would like! We use them in my sons nursery so that when we have a night diaper change he doesn’t get fully woken up. They work great and I love using them with my google!

    Got these as a daily special. They are "fine". They're not as good as the Phillips Hue bulbs I have in another location. They occasionally don't respond to the Google Home commands.
