Drops WiFi Signal

Everything works great. Light changes to any color, and it plays music through the bulb which is really cool. It also will change color and flashbacks a strobe light if you have it on auto with music on.

But when I'm just sitting without music and I have the light on I here a loud click a couple of times a minute. If it lost signal once or twice a night I could understand but this is ridiculous when I'm trying to watch TV or read.
I'm putting it my kids room as he will enjoy it. The clicking is just so annoying.

!!!!!DOES NOT WORK!!!!!

Picked up 3 of these. Have had them for months now and I have never been able to get one to work for more than a few minutes - and then only after untold attempts trying to connect. Very frustrating and apparently NO effort by the developer to fix. In fact, I'm not sure there is any intent to correct this or that the developer cares as it seems there was not much effort given to make/translate this app to the English speaking market - the language on the connect screen is barely discernible as English. "Buyer beware" should be on the packing for the bulb- but since the bulb packaging is done so much better, then, like me, most won't know until it is too late. I now have 3 useless (expensive) bulbs; yes "useless" because the bulbs themselves will beep loudly periodically as if they are awaiting Bluetooth pairing!!!

Love this bulb!

I got one of these light bulbs about a year or so ago, and lemme tell you it’s great! I use it all the time and it still works flawlessly. I love the changing colors features and the option to turn the light off while it still being able to be active like play music and stuff. It’s very useful for me, making videos in different colors, which will stay even after I disconnect. Love this light. My only request at least would be to modernize the app a bit. It works just fine but modernizing it’s style would be nice. :)
