I bought these "Used - Like New", for less than $10! This was a great deal. I was hoping that the reason they had so many used ones, was that they were difficult to set up for non-techie people, so many people gave up trying to set them up, and returned them. It seems that I was correct. The bulbs were perfect, and I couldn't really tell that the package had been opened. Set up was difficult enough that I could see why some people may have sent them back. However, with just a little trial and error, I was able to get them to work. I am very pleased with the many choices of lighting scenarios, and the ability to make custom ones. I am using the Cync App, and I also can use Google Home, and Google Assistant to control them. At first I had all of them in the light fixture and tried to set them up, and I ran into some problems. When I finally decided to put one bulb in the fixture, set it up, and then put the next one into the fixture, set it up, and so on...I was able to set them up with ease. Don't be afraid to buy the "Used- Like New" ones. I may buy another set as a backup.

My initial review upon install is that the lights are great and set up could not have been easier, just follow the directions. Download the app, put the light in and turn it on, follow directions. I am using the light outdoors in a covered lamp, so we’ll see how it holds up, this is not a recommended usage. I bought these to match our exterior lights which can change colors, and the color change on the app could not be simpler to use.

Fun product. Commission each bulb individually in Cync app and then pair or group lamps you want to work together. The app is a little clunky, but it works.

I really like these bulbs in my ceiling fan that has chandelier bulbs. The color options are phenomenal and whatever color you can think of to say to your device it’s connected to, My Alexa does it for me!!!The brightness of the bulbs are insane and will light up everything in your room and you can make yourself a night light too!!One helpful tip I will tell you, if you’re putting them in the same thing like I did, with my ceiling fan and it has three bulbs, I had to take the code off of each individual bulb and scan the sticker to add the bulbs to the app and it took Me a hot minute to try that out and Thank goodness it worked out perfectly!!!It didn’t take any time to get everything connected and functioning after I figured out the bulbs had to be done separately..As soon as you tell your device, what to do with your bulbs and how you want them what colors you want them and you can make each individual bulb a different color, like I do to my ceiling fan. if you want to, it’s all your preference.As quick as you tell your device, what color you want or to turn your lights off or on, it’s on in a quickness and you can’t beat that!!I’m sick in those days I can’t get up and down sometimes not at all, so I’ve turned my bedroom and my en suite bathroom into a place that I don’t Have to get down to turn my bedroom lights off and on And it’s a wonderful feeling when you just tell them what to do and they will just do whatever you want!!!

Unreliable and longer than other bulbs. I had numerous issues with the bulbs "losing" the wifi and having to removed and set up again. I loved the colors and patterns but not worth the extended, open ended investment of time. I'll keep my Cync outdoor lights. They work perfectly. These aren't worth it.

Finally a candelabra bulb from GE CyncNow can add my ceiling fan lights to the mix

I chose these bulbs because they were well rated and reasonably priced. Set up was straightforward and the app made it easy to control the bulbs. I like the dimming feature, and the ability to change the tone of the white light. Warm white is my favorite. The color light options are rich and beautiful. However, due to the plastic “smart” base of the bulb (which is the lower third), the bulb does not fully illuminate my milk, glass shade. If I had a standard clip on shade, it might not matter, but this was not the best ball for this type of light.

Easy to set up using the app. It's nice to vary the colors depending on the time of day.
