So I've been using SENuke since X was first launched, yes it's probably cost me well over $2k by now ^^ It's improved month on month and has never let me down.
I run a campaign for each of my sites for 30 days at the beginning of each month after updating it to get the latest sites and modules etc... for the software.
My overall rating would be 8/10 for SENuke XCr -
The only few downfalls it has -
They removed the Video Module (Which I want back, but sadly was confirmed it'll never come back)
The Turbo Wizard is fantastic but sometimes it gets stuff wrong, if it somehow doesn't spin the content or has no response from the spinner - It'll just post the same article over and over (duplicate content #NONO) so you can actually get a bad backlink. That's why I tend to only use it for 2nd tier link building from my authority sites.
Otherwise, it's probably the #1 Link Building software you could get - Great value for money as you get all the modules for every type of link building (except video) you'd want to do - You can even add your wordpress blogs and have it post content with backlinks, so if you run a large blog network - Import all the domains and user/passes into senuke and let it build backlinks to your other sites or your clients.
Hope you enjoyed my short but sweet review,
