I've been waiting a while to add more of these to the home setup - they're usually around the $30 (or higher) mark.
In lieu of any other decent (and decently priced) switches that can be used in Australia on Philips Hue and LIFX^ bulbs, this remains the switch for me (albeit by default).
Rumours of LIFX releasing their own switch have been circulated, but nothing confirmed that I can see.
Enjoy.
^ To control LIFX bulbs, Hue hub & an Apple device (eg. iPad or Apple TV) required, it seems. Not sure if possible with Android.
EDIT: Black Friday price $19.40! Go get some!
I saw it at this price few days ago, but want to wait till tomorrow to see if Amazon runs the deals on Philips Hue again.
