So my main complaint is the cheap lamp assembly. One has already broken because I was moving my floor lamp and the glass of one of the lamps fell out of the bulb and shattered on the floor. No injuries but no fun getting the rest of the bulb out of the socket. Otherwise it worked with Alexa. The QR code worked for the first bulb, but subsequent bulbs gave me a "bulb already added" error, so I had to add it to the LinKind app over the bulbs' Wi-Fi.
