I have read the reviews and wasn't sure if these would work fine as some people said about connection problems, mine have been woking fine (just now one didn't turn on with the rest) but I think that can be expected as these are wifi and you will get interference for time to time depending on where abouts in the house they are located and how good you wifi is, mine are housed in metal sockets down stairs with my router upstairs and like it said been working fine.The only bad think about them is the software, can't group them in smart things app, have looked at how to do this and they should have a way to look at the setting/properties to group them but they don't, other than that I can control them fine with colour and differnt white settings and can group them in the alexa app (this does mean can only group them once), I will be buying more to seem how many I can have on my wifi. Ps the colour is dimmer but it does state that, the white is bright.
