Did find the initial setup somewhat difficult, i.e. they would sometimes fail to setup and you would have to reset them and try again. We also had one out of the 4 bulbs begin to malfunction after a few days, but LIFX was super easy to deal with and they sent a replacement no hassle.
The dimming and dusk settings are fantastic - exactly what is advertised. Also the colour and brightness can be set with google assistant.
Have not had them drop off the network and have worked flawlessly with google assistant. We do have a fairly good mesh setup, and the worst would be a slight delay in a command, but very tolerable. Phone app works fine too.
Be careful about the clearance you have for where you are installing the lights. These light are a little bigger than your standard globes, so if there's a cover it may not fit back on.
Had been looking for a while at smart lights and we're very happy with our LIFX.
