My 2004 is an early one, zero problems except for the backlight, and when I killed it when I modded it with an S-Meter and some other stuff and shorted something out when I left it turned on while working on it Dumb move on my part. G&G fixed it by transplanting the whole top board from a donor 2004, and it's worked ever since. The keypad is worn out, to put it mildly, and I modded the backlight so it could be turned on or off, not just dimmed.
My HP-1 worked great, sometimes, but it would randomly lose most of it's sensitivity to the point it would barely hear the local WX transmissions that normally blast in. hard resetting it multiple times would restore sensitivity, until it happened again. After a month of this, I sent it to Uniden, who found nothing wrong, but right out of the box, it was deaf again. Off to Ebay it went, same as my PSR-800. The SD card issues and the general deafness of it were too much to tolerate,and off it went too. If a radio works well, I tend to keep it until it's a senior citizen, but the last new scanner I've had worth keeping is my Pro-197. The HP-!, 396XLT (Bad audio, it worked fine), and the PSR-800 were all gone within a year. My Pro-106 and PSR-500 are pretty old at this point, but they work every time I turn them on, without any drama. It seems it's too much to ask for the new ones. Maybe it's just bad luck, but it seems a lot of people are also having similar experiences.
