Review on 🖥️ Portta 4PET0301SS: Advanced 3x1 HDMI v1.4 Auto Switch for 3D, 4kx2k, 1080P by Michael Hughes

My old 42" Vizio LCD TV only has two HDMI inputs, but I have a DVD player, Blue Ray player and Apple TV, that require an HDMI connection, so I bought this hub so I can connect all three to my TV at the same time. At the moment I have an apple tv and a blue ray player connected to the hub's two inputs, by pressing a button on that hub I could switch between the apple tv and blue ray player and choose what I want to use. However, I was hoping that this hub would automatically switch for me if I turn one off and the other on, at least the name says it's "smart". Another thing is that somewhere in the description it says that this hub is battery powered, but I couldn't figure out how to change the battery because there is no battery compartment or anything. If there's a battery in there I guess I'll have to use a screwdriver, ie take it apart first. Well, I'll take care of that later
