The 404 is a very basic scanner...no 800 MHz, no trunking, no PL/DPL.
So I guess the real question is: Did you do your homework before buying it, to make sure it was capable of receiving the frequencies and agencies you wanted to listen to?
Also, we have no idea if the scanner is a "waste" for you, since none of us are mind readers and have no clue where you live or what specifically you are trying to listen to (not without searching for your other threads...it would be helpful for you to put your location in your profile, or be more specific in your posts)
