I have the four port model, works fine. Good quality overall. Used almost four devices at max to charge, laptops, mobiles, cameras never did overload or heat up.
The only downside is that would be better if the individual ports had individual switches but for the price range is good. And if we use heavy adapters or plugs the main box will tilt over depending on the plugs weight. We will need to distribute the plugs weights to prevent the box from tilting over.
The main plug wire is of decent length so don't expect the box to move around the entire room.
