As ubiquitous as I think these things are, I'm either preaching to the choir or being mind-numbingly repetitive here, but here goes. Got one yesterday, but had to wait til today to check it out because... First comment... Have a good screwdriver. The very first step is to take the case apart and position, or check, a jumper. I don't know how they put those screws in, but you'll need a hefty screwdriver or ratchet to loosem 'em. They're very tight. But the good news about that is you're forced to open it up, and that's a good chance to see if, maybe, you got one of their famous "semi-kits." The construction looks to be 98% printed wiring, and I'm guessing that since that's probably wave solered, there's a good chance that there will be no cold, or non-existant solder connections. I think the only part that's not directly soldered to the board is the battery holder, and those connections looked good. Comment #2 Pretty much lifted from another review I read -- the power button is very easy to turn on. In fact, mine came with the power button in the "on" position. An easy "fix" for this is to plug in a 2.1mm power connecter into the power jack. That will effectively act as a "safety", and the unit won't turn on with that inserted. So I measured the SWR of the rubber duck from my handheld (only thing I have here to test), and was pleased with how easy that is. As I've read before, "How did I live without this?" It seems AOK, and I can't wait to get home & try it with the various antennas/tuners I've got. Oh....and, in case you don't know, it also does a whole lot more than just measure SWR.
