I've got three sets of these two of which are from amazon Germany (paid around AU$99 shipped for each) but I have to put an AU adaptor for them. These ones are AU$99 ($124 with 20%off), good price. I have over 50 Wifi connected smart devices at home and overall Phillip devices are quite robust. It works great with Alexa but you must have a Phillips Hue to control it. It will not work standalone.
