Alexa friendly
These bulbs are nice and bright. You can tell Alexa to dim them to 50% or 30% whatever mood you need.I can be sitting in the living room and tell Alexa to turn them off and not have to keep getting up every time my husband goes to the kitchen and leaves the light on. ;). Set up was pretty easy too.

Love these bulbs!
I was a little skeptical about using these regarding some of the reviews about connectivity, but so far, these are fantastic. The light is just warm enough to not be a yellow tint like others I’ve tried (i’m picky about this). Using with an Alexa has worked great and my kids are getting a kick out of using Harry Potter spells to turn the lights on and off. At full strength, they are pretty bright. It would be nice if they dimmed a step more, but they are nice mood lighting at the lowest setting. Will definitely keep using these.

Great bulbs (-1)!
Great product. I am actually using them in a stoplight that hangs in my garage. I created a routine in Alexa that changes the stoplight at different times during the day by using these bulbs. No problem connecting to the internet at all. Very pleased.3/6/21 update: still living the bulbs but ism dropping my rating from a 5 to 4 stars because I ordered another set (for a second stoplight I acquired) and one bulb failed right out of the box. For around $10 per bulb, I expect better. I know it was probably a one time thing but wanted to mention it here and adjust my rating.

Easy to install, set up, and voice control
We have them in two different rooms of the house and hooked up to Echo/Alexa. No problems, easy to turn on and off and they’re dimmable. The initial set up went easy if you follow the instructions depending on which type you have. Be patient. We have had them for 2 months and no problems at all.

Not worth the headache
At first, these bulbs worked great; seamless set-up and connection to Echo Dot, voice commands working perfectly, and really great light brightness. Since purchasing these bulbs a little over a year ago, I have battled with them at least 10 times when they decided to stop connecting to the WiFi, thusly losing connection to the Geeni app as well as Alexa. The bulbs will randomly turn on in the middle of the night and enter pairing mode, which is an annoying strobing that does not stop until you either successfully re-connect it through the Geeni app or you cut the power to the light fixture.Super disappointed, since the style and brightness is great when they work properly. Buyer beware!

Wow! What a pleasant surprise!
I bought this for the pendant light in my kitchen, and I love it! It was easy to set up the bulb after I called up their customer service. They explained to me that all smart products only work on 2.4G WiFi, including all the big brands. I use a 5G band but it turns out this automatically comes with 2.4G, I didn’t know that. I connected with 2.4G and the bulb connected instantly. I am going to order a few more for my sister and mom!

Not Bad
The Geeni smart plugs are fantastic and work wonderfully with the app and google assistant. These intelligent lights did not perform quite as well as the plugs or LED smart strip purchases. The color/brightness options were terrible and hardly noticeable, additionally 1 of the 4 purchased continually lost connectivity to my network. I like Geeni products but these lights are simply not ready for prime time.

Great bulbs, terrible app
The bulbs work great with Alexa, but the Geeni app is absolutely terrible.

Yup. It works as advertised, and so easy to connect!It is really bright at 100%, but it’s dimmable!”Hey, Google; turn the dinning room light on at 5%!” “Turn up the lights to 75%” “turn the lights down to 20%”….. so easy. who needs a light switch?All the sudden the dinning room is the fancy restaurant that turns the lights down for the moody crowd…
