Just like 90% of the wifi smart plugs, theyre just too bulky. I know the technology exists for them to be slimmer as Ive purchased smaller ones. At least they could be square and fit with two in one socket.
The app works pretty well and it pairs with alexa simply enough. Once in a while they become unresponsive and youll have to unplug them and plug them back in. All in all, a three pack for the price isn't too bad.
