I'm very happy with this purchase. It is a little smaller than I thought it would be but the light that comes out of it is excellent. Having so many colour options means, you can set it to the mood you're in. Even my wife, who is not keen on all this technology, is very impressed with it. I am using it through Amazon Echo Show, I don't have a Philips Bridge. This means, I have to use the Alexa App on my phone to operate or voice through one of my Echo's. Alexa, discovered the lamp straight away and it was set up within a minute - Very easy. Being able to use it without the power plugged in, is a bonus, as I can take it outside when needed. Not sure on the battery time, as I haven't run it for a number of hours yet.
