Congrats. I am glad you are getting your name and this eBook out.
One piece of advice from a semi-professional marketing manager - Exclusivity vs Mass Marketing. When I saw Jacob mention not liking the writing style, it peaked my interest even further and took a look for myself. Although the kind words towards your eBook are nice, because it is your product that he is writing about, as the creator - you might want to politely ask for some more professional editing of his review. The writing style is quite amateurish with some common vocabulary and grammar mishaps and ultimately, this can hurt you almost as much as it will hurt him.
The purpose for having your product reviewed, is to get the followers of that blog to learn about your product. This is why press releases are written over hours and hours of editing and very respectable blogs sift through hundreds of emails deciding on which items to feature, because in the end, it is their reputation on the line and representing a fail product lowers their image.
I am not saying this is the case with your eBook on his site, however, I feel he might be getting the better end of the deal and that your fans and followers on the T11 site will now be going to his site because of you, when it should be the other way around.
Again, this might be all misplaced speculation, but it is the first impression that I got from visiting the site and reading his review. If this is something you are doing to help out a friend and his blog, then I think it is great, but perhaps help him with some of the phrasing in his reviews. You can help each other grow.
Cheers,
