    This part was weird ... After I tried connecting to that plugs network my app automatically recognized it and the device was added to the app, huge hassle to set up due to my GHz being way faster than what these guys wanted but in the end it works and is probably the cheaper way to go than buying smart LED bulbs since you don't need a hub

    I've always wanted to start transforming my apartment into a smart home so I ordered these thinking they would be a cheap way to start, well they are cheap in price only, the quality is really nice and impressive considering how much I paid for the two pack, they are a great value and work really well

    This device works great in my home, you may reach it from your private wireless network but not the other way, this will keep the private part of your network private, and Voltage as well as cumulative daily and monthly power consumed through the smart plug

    Once I was connected the product works great, if you are using a sing outlet this product would be great however if you have two that you want to smart switched to go into I would recommend looking at some of the other slimmer more compact models

    We all know the frustration of tech and connected device that don't deliver ... The smart plugs are what we all hope for in a smart home product.Quick and easy set up with a won't - break-the-bank price point, I don't write many reviews

    It has a timer setting but I think I need to leave my phone in the house for it to remember my settings otherwise when you leave your synced device from the plug it forgets everything but to turn off

    I used it with Alexa to turn a lamp on and off and it does a great job with barely any delay, the size is also really nice because it won't cover both wall plugs like another one I have

    One unit works well and the other one intermittently reads offline from the companion app, I use the smart life app since it works well with Google home and ifttt

    My experience with a smart plug is with an older WeMo that is much larger in size takes up the whole outlet if in the bottom socket and it doesn't track power used
