    Smart Lights

    Were very easy to set up, but my internet connection was slow so it took some time. Many different settings to choose from. Color settings are very fun!

    Gave them away

    Wasn’t able to get these to connect to my network. May have problems due to it being a combined 2.4/5ghz. Didn’t bother to troubleshoot further. Gave them away to a friend. Friend had same issue of not be able to connect to them to the network.

    Edit: I’m well aware that I need to connect these devices to a 2.4Ghz network, as well as my phone. However, this is the ONLY bulb I have ever purchased that refuses to connect to a 2.4/5Ghz and detect that there is a 2.4Ghz connection avaliable. They may work just fine if I went into the router and separated the signal, but being as every other smart home product I have ever used never had an issue with this, I shouldn’t have to.
    Bulb came shipped in good working condition and is bright.

    brightness very dim

    these light are easy to connect and navigate however the lighting when in color is super dim. I have two bulbs in my light fixture and this is the brightest it gets with TWO bulbs. I have smart bulbs from other brands that give off way more light. I give three stars because I guess it gives the quality of the price of two bulbs.
