    Good, but some connectivity issues
    The Kasa Smart Light Bulbs offer a convenient and customizable lighting solution with their full color-changing and dimmable features, compatible with Alexa and Google Home. However, while they have their merits, their reliability in staying connected to the internet leaves something to be desired.On the positive side, these bulbs provide a wide range of colors and brightness levels, allowing for personalized lighting to suit any mood or occasion. The integration with popular smart home assistants like Alexa and Google Home adds to their versatility, enabling convenient voice control for seamless operation.That said, the inconsistency in maintaining a stable internet connection can be frustrating and impacts their overall usability. There are occasions when the bulbs fail to connect or become disconnected from the network, disrupting the intended lighting settings and requiring manual intervention to reestablish connectivity. Often just one will disconnect, meaning I can’t control them both at the same time. Other times, both disconnect.While the lack of a required hub simplifies the setup process, it seems that the reliance solely on a 2.4GHz Wi-Fi network may contribute to the connectivity issues experienced by some users. It's worth noting that in environments with multiple smart devices or interference, these issues may be exacerbated.In conclusion, the Kasa Smart Light Bulbs offer a decent lighting solution with their color-changing and dimmable capabilities, enhanced by compatibility with popular smart home platforms. However, the inconsistency in internet connectivity detracts from their overall reliability and usability. For users seeking a seamless smart lighting experience, it may be worth exploring alternative options with more robust connectivity features.
