The part about maker channels clearer and stopping the lines from the lower stations is false I think it made it worst since i had hooked it today since I recieved it. I unhooked the cable wires and just left the items plugged in and it seems to work better. So the part about making your viewing better is false. As a surge protector hopefully that is true and works and the guarantee about the equipment is true hopefully i never need to find out but I guess it could be a sense of security from surges. I think if I can return this product I will and get a cheaper one like Belkin or one that is warrantied for life. I think this is anexpensive piece of garbage, thank god i didnt buy it at Best Buy where its $80 more.
