This item works as advertised but the real story about this purchase is the customer service I received. Outstanding reply to a small problem! I hooked these up to my EchoDot and it worked fine, dim, change color etc. Except, when I told Alexa to make them white she replied with OK but they didn't change. Contacted customer support, they found the glitch in one day, posted an update within two days and the problem was fixed. So nice to see a company care about their product with such enthusiasm!!!
