Very easy to setup on your tv. It is literally all about positioning which channels you will get to display and even slight movements can cause your channels to become fuzzy. If you put it on a flat surface where it wont be bothered, preferably closer to a window; you'll get free over the air digital tv.
Definitely worth it if you are trying to save money on cable services and just want channels to watch with no exact preference.
I gave mine away to my grandma since she would get more use for it, and is looking to save money on cable. I would recommend this as a money saving high quality inexpensive alternative to Cable. The TV has much more channel for her to watch.
