Review:
I purchased this software as a Black Friday deal 2 weeks ago, and I've used it for several days continuously and my honest, unbiased review is that it's worth the money. I've already found several dozen articles in the niche that I used the software for, and that niche is pretty small in itself, so I'm thinking that you can literally find 1000s of expired articles after a few days of use were you to let the software run continuously (although it does require a bit of interaction between projects, to filter the bad results out, load new domains up, and so on)
Anyway, for what it costs it's definitely worth the money, it's pretty basic in itself (only scrapes WBM for expired content) but it's very good at it, so I wholeheartedly recommend it to anyone who has expired content as part of their business.
Also, I just talked to OP, complaining about a few things that weren't working for me and he already fixed half of them before I even got home to read his reply. And that's the 2nd update in 2 weeks since I've purchased the software, so the support is great in what concerns me.
That was my (unrequested) review
