Beantech Smart Plug 4-Pack WiFi Outlet

I downloaded the “Gosund” app by QR code on the box and followed the instruction, but it can’t connect to 2.4G wifi. I contacted the customer service provided from the app. The tutorial video and steps they provided didn’t help either. I tried all of the 4 smart plugs. None of them are good for EZ mode or AP mode. I didn’t realized the “Gosund” smart plugs was not right product until I contacted Amazon customer service. They told me it’s different app and different brand, so they sent a replacement. But it’s still Gosund…. and still not working. I got it with a good deal. However, it’s useless if it doesn’t work. Had to return it.
