I used this product to live stream the World Cup Final for a big community event. Now, when plugged into the left hand side it did interfere with WiFi but it’s an APPLE PROBLEM not this device. A quick google search will confirm this. Plugged this in on the right and the streaming and picture was perfect. It does get warm, but absolutely nothing of concern, I defo wouldn’t call it “hot”. Sound stream from it perfectly too. Absolutely no cons with buying this.
