I would have given this a full 5 starts however, the lag between pressing the button to it showing on screen was a good 5 ish seconds between clicks, also no batteries included.
Other than that the device takes a few minutes just to get plugged in then it just works. Picture quality was good and didnt notice any downgrading of the picture.
Had this one running to an older Panasonic TV, with BlueRay, FreeSat box and Firestick.
