Review on Recessed Lighting 2700K 6500K Selectable Downlight by Elder Unogu

I bought it to replace the recessed lights in the kitchen. I have 4 inch recessed lights in my kitchen and wanted to turn them into smart lights. I was very excited when I received this. In the beginning, the lights stay connected well to the hub, which was about 10 feet away and on a different floor. After 4-5 days the lights stopped connecting to the hub and in turn stopped connecting to the Alexa phone. I've invested a lot of time, but all in vain. Very disappointed with the quality and performance.
