I haven't personally heard about that one in particular, but since I don't have much experience in the Windows world of Sniffers, what I CAN say, is that Doppy is someone I personally trust.

So, for what it's worth, if Doppy gives something his stamp of approval, I'd say it's worth at least checking into. When he responds to a thread and has a tool he's recommending, he seems to almost always pick very well, so look into it!
