I have an Amazon smart plug and these Kasa smart plugs by TP-Link work just as well. Once you have the Kasa app installed, setup was a breeze and took me less than 2 minutes - including updating the plugs to the latest software version. It is very well integrated and were discovered easily by Alexa w/o any hiccups.
Once that is done, you can group them together however you like. I even create scenes using geo-fencing that will turn on my kitchen lamp when I am near home. I planned to use one of them for my Christmas lights. This way I don't have to bother with the old timer like before.
The plugs feels solid and high quality. The side power button turn on manually with a satisfying click. The Kasa is actually a little smaller the Amazon smart plug. Long term, I have an older TP-Link plug I bought over 2 years ago and it is still working like a charm. Haven't experience any disconnect from my home Wi-fi yet.
Why get just 1 Amazon smart plug when you can get 2 of these for the same price, built, quality, and ease of use.
