It works as described. If you have a booster for your antenna, remove it or turn it down. The channels will come in more stable. I've tried so many boxes, I lost count. I enjoyed this one so much, I ordered another one. You don't have to have Prime an order to get your packages in a reasonable amount of time. I am satisfied with this purchase and most of my other many, many purchases from Walmart and the sellers on this platform.
