    These arevso great! I put 2 in a chandelier which had no dimmer. Now it dims in many shades of white as well as tons of colors. It has preprogrammed light shows or yiu can manually create your own. Easy to set up and really fun

    Love theese bulbs. They do exactly what you think. Can do basic from change to a warm yellow to nice crisp white. Can create custom shows with colors and patterns. Can set them to turn on and off at certain times of the day or choose to follow the sunrise and sunset times. I personally love theese bulbs and they function as exactly as advertised and some. The app is extremly functional and ive experienced no issued after 6 (ish) months of use.

    These lights are so cool and really unique due to having multiple colors showing at the same time instead of changing from color to color like other brands. Worth trying out and playing around with all the options via the app. Easy to connect and set up.

    The dynamic effects are the new standard. I highly recommend these bulbs. The fact I got them on sale is practically a steal. Ideal for setting an atmosphere for any occasion. To see this kind of technology in a light bulb is something I never would have imagined

    Had a cheaper version but saw this on sale, and grabbed it. It's perfect for changing the colors of my lamps around me when I game. It responds quickly to the app, very easy setup. A good alternative to those more expensive ones. I'd replace all of my lights with these if I could swap out the custom bulbs.

    Wanted to liven up the room a little. Figured i would give these a shot. They were easy to install, the colors come through great with my ceiling fixture that has a slight yellow tint. The app to connect the bulbs was quite easy.

    The two pack is so worth it! It syncs together and light bulbs are then able to be controlled with your phone. The vibrant hues are a vibe and when you want something subtle, it’s dimmable. I’m not a fan of yellow lighting so this bright white is a win for me. Will be purchasing more for my house.

    Loved the idea of the bulb and was so excited to use it with my grandchildren. I was in total shock to know you have to pay a 1-year subscription to use the bulb (approx. $100). But love the idea of this color changing bulb and was not signing up for a year at $100.00 unfortunately. So, I had to return the bulb.

    Works well, and color selection is quick and snappy. Unable to select a specific kelvin level like Nanoleaf bulbs but the colors you get are deep and dark, and not the best as usable light. The app just needs a few final touches to make it more customizable.
