got one of those too and i hate it, burns through batteries and it's got a big ass split tip that's way too hard to use and it seems all i've been able to do is melt the solder on top of everything, i can't get it to fuse or join or whatever it's called, but anyway, i hate mine and i've only used it twice, probably get a different one soon... great idea, just doesn't work... kinda like those stick on antenna boosters for cell phones... when i worked @ radio shack, we sold them like hell, and people even swore they worked, but i've yet to see any results... anyway...
