I purchased this to replace a set top/blue ray combo. The unit is tiny not just in comparison to the combo unit. Very easy setup, took minutes. Recommend making sure you have quality co-ax (aerial) cables AND connections as it is a HD unit, don't blame the set-top box if your signal is glitchy. My nine year old was able to drive it straight after it was set up. Only complaint is that it doesn't use generic station numbers such as "73 for 7 mate" but I'm sure it's just in settings (?) EPG is very good also. The quality of picture on our Samsung panel free to air TV is so much better.
