Love this plug, set up was as easy as... plugging it into the wall. Pulled up my Alexa app on my phone, checked for new devices, named it LAMP, then plugged my lamp in. "Alexa, turn the lamp on' "Ok!" -And there was light. Such a treat, to be settled back in the corner of the couch with a comfy blanket, tea, book and a cat, and be able to turn the lamp off and on without getting up. Worth every cent I paid for it. Well it would have been if it had cost me anything; got it included with a new Echo Dot, so even better. Love this convenience. Not sure how it would work with other things, some don't need voice control, like the TV... it's actually easier to press the power button on the remote in my hand than it would be to waste a plug so I could tell Alexa to turn it on instead. So there is that.
