These things are way lighter than any other smart bulb I have.
They lose connection often, and worst of all: buzz when on any normal "light" color (ie: white, daylight). Work great for weird colors, though. I just wish my rooms didn't have to be "lemon chiffon" if I need to look for something.
Love these things! They make me feel like I can do magic when I control them from my phone. (Still working on mastering them with just The Force alone.) I bought two for my bedroom lamps and don't even need a smart hub to use them. Just Bluetooth and the Sylvania app. The only critiques I have are for the UX of the Sylvania app and nothing to do with the bulbs themselves per se. Very pleased I got 2 for $10, good deal. Cheaper than what I paid for a single one of these bulbs a year ago in a store's clearance section.
Nice product but requires an updated Amazon Echo device
Nice product but requires an updated Amazon Echo device. Bulbs were unresponsive for Echo Dot 2nd Generation, but working very well with new Echo Dot 4th Generation.
