I got one of these for a friend, and it was working great for a week, so I thought I'd pick up a few more. At my house, it set up easily at first, but then it stopped working. I traced part of the problem to the fact that it seems to be pairing with only a single one of my amazon echos -- my Echo Show 1st gen. Unfortunately, this Echo Show is flakey and goes down every now and again. When it goes down, this led light bulb stops working. Even though I have several other echos that are supposed to be able to talk to the light bulb, they won't. That's not all of the trouble though. When the Echo Show 1st gen comes back on, it doesn't seem to re-connect to the light bulb right away. Perhaps it would eventually, but it doesn't reconnect in a couple of minutes. Maybe it won't ever. This would seem to be a problem not just for flakey Echos, but also for power outages. Another issue is that the light bulb refuses to pair with any other Echo besides my Echo Show 1st gen -- even if I reset the light bulb. If the Echo Show 1st gen is unplugged, the light bulb can't be discovered by Alexa. After connecting the light bulb and then turning off my Echo Show 1st gen, Alexa also seems to temporarily forget the name of the light. It's still in my list of lights on the Alexa App, but I can no longer ask Alexa to turn it on or off by name. This seems to fix itself in a little while. And of course the light won't turn on or off from the app when I've turned off that one Echo Show 1st gen that it seems to rely on. So I initially decided that this light bulb should be avoided right now -- but further experimentation changed my mind. (Amazon support was useless. I had to figure this all out on my own.) Edit: I finally did manage to get a different echo to connect to the bulb via bluetooth. What seemed to do it is (1) unplug the echo you don't want it to be connected to. (2) reset the bulb by flicking it on and off five times, at which point it blinks three times to verify the reset. (3) unplugging the echo that you want it to connect to, and then plugging it back in to reset that echo. This seems to make it forget that some other echo was connected to the bulb. (4) asking that echo to "find my devices". (5) plugging the echo that the bulb was originally connected to back in. Additional Edit: after making sure the light bulb was paired via bluetooth to a newer Echo Show 5 instead of my old Echo Show 1st gen, the LED light now works well. If the power goes out to the Echo Show 5, the light bulb stops working while it's rebooting but then starts working again as soon as the Echo Show 5 is working again. So there won't be a problem with power outages like when it was paired with the Echo Show 1st gen. I believe the reason many people are having problems with these bulbs is that they have older Echo devices and the bulb doesn't work well if it becomes paired with an older Echo. So when you first set one of these bulbs up, I recommend you temporarily turn off all your oldest Echo devices so that when you discover the bulb it doesn't pair with one of them. This is the only way I know to have control over which Echo it pairs with. If you want to know which Echo it actually did pair with, try unplugging an Echo. If it's the one the bulb is paired with, the bulb will no longer be controllable from any Echo or the Alexa App, until you turn that Echo back on. Although turning the Echo back on may not restore operation. As I said, it does restore operation when paired with my Echo Show 5, but it does not restore operation when paired with my Echo Show 1st gen. I'm raising the review to 3 stars, since it appears now that it can be made to work reliably if you own a newer Echo device and turn older Echo devices off during pairing. I'd give it 5 stars if they actually had instructions and warnings guiding people through these perils. I appreciate that this light bulb doesn't come with a privacy policy. Many of the other bulbs do, since they can only be set up from an App with a EULA and privacy policy and connections to who-knows-where on the internet.
