BUY THEM!

I Love this light bulbs, at first I had GE ones that unpaired all the time and it was a pain to reset them to connect them again and even then it didn't work sometimes, I came across with the brand Mercury while looking for a new light bulb for my son's bedroom that could use as a night light and because it was cheap I got it and oh boy!!! I was so surprised that it worked even better than the GE ones so I got more and these are the ones that I got for all my lamps and lights in my house, they are easy to connect if you follow the instructions and use common sense, now most people have two types of wifi you just need to select the 2.5 one and they connect super fast, also google recognize them automatically if you use yhe geeni app! They are really nice to create a nice ambience!!!!

bought for my lamp in the living room. one was broken and I am guessing due to shipping other than that I ordered the four pack also and since it is LED I have seizures so it is on the lowest setting and I had to leave the room when my daughter sat up the program on it. WHY IS EVERYTHING LED? DO THEY NOT TAKE US SEIZURE PEOPLE IN TO CONSIDERATION? Besides that, with it being in a low setting, I have no problems.
