Bests & Worsts Reviews from Amazon

I have had this for about a month and really like it. It works consistently both with the app and Alexa. Installation was easy too. The best feature is that it is more energy efficient than competitive switches. I bought a Leviton switch initially (DW15S-1BZ) and found it disconcerting how warm it was. I bought this TP-Link switch and installed it in another room to compare. This switch is cool to the touch. It uses a little bit of power even when the light is off, but not a noticeable amount. The TP-Link Switch is about 8 degrees warmer than the ambient room temperature. In comparison, the Leviton switch was 20 degrees warmer which is warm enough to notice. My biggest compliant is that it requires you to push the lower section to both turn it on and off. When you go to turn it on, you expect to be able to push the top. Nothing happens there though (you can't depress it, so you know something's not right). When you push the lower section, it will toggle on/off. It works great, but isn't as intuitive as the Leviton switch which allows you to use the upper/lower section to turn it on/off. Even so, you adapt quickly. I plan to buy more of these despite this shortcoming. I attached some photos showing temperature measurements on this switch and another one. Both are off. It shows this one is much cooler because it is more energy efficient. Temperatures were taken using a Fluke IR temperature sensor. I also took current and voltage waveforms using a Keithley DMM7510 (see various attached screen hots). I found the power to be about 0.5 W when the switch is off or 1.62 W when the switch is on. This was 3 times less power when the switch was off when compared to the Leviton switch (1.86W whether on or off)
