Top critical review
Works as intended, but would not buy another one.

While useful, the fact that it only allows one action for each button is not ideal. That is, each button can be a scene or a state, but not cycle through and you will need another button for off state. The other Philips switch is more practical, unless you need a battery free alternative.
UPDATE: You can modified the operation of the device using Philips developer kit, API commands and JSON.... if that made sense to you, then you will find altering the commands so that a single button pressed once turns on, pressed again turns off - this way you can have this remote control multiple rooms, even one button for on/off the entire setup.
If not, then you will either have to stick with the basic function or look at alternative app to control your Philips Hue setup that allows customised buttons - you will have to pay for this.
