This is a sturdy fork. Setup was a problem. I used my phone - bluetooth should be on. You must select "Auto Search" before doing anything else in the app. Then you need to select "WIFI socket" (offers a long list of items). With 3 sockets to 1 plug I was expecting to be able to group them into 1 schedule but no. You must plan each outlet individually. I have separate WIFI sockets from another company and I can "group" them, so it's very strange. It does the job.
