Lamps are very bright and have an excellent range of colours. I had to install a separate app to integrate lightbulbs with Alexa, but it wasn't difficult. Occurs with recurring "device not responding" issues where one or two lamps are responding but one or two others are not. I can't say they are "easy to use". I have another brand of bulbs (will remain unnamed) that work much better and although they cost a little more I think I'll buy some of these.
