I got these to replace my Sengled bulbs that I used as smart bulbs with Alexa. The reviews are good. I bought the MATTER level so they link directly with Alexa and I don't have to have a 3rd party app or skill (which was the downfall of the Sengled bulbs). Most of them linked up and worked right out of the gate (I bought 12, installed 10). A few of the bulbs I had to delete and reset up multiple times before they would work in a group or stay connected to Alexa. Keep at it. Eventually they'll work. Note: these will not work on a reostat, dimmable wall switch. You'll need to replace the wall switch with a regular switch.
BEWARE: Sengled bulbs are no longer supported by ALEXA. There is no Sengled skill for Alexa. If they are a zigbee bulb (it'll say zigbee on the bulb), you can link them to an Echo device hub. Remove them from the Sengled app first. If they are just a Sengled bulb, you now have a non-smart LED bulb. I don't know if they still work with Google or Apple.
