Feedback on Book Linking Marketing Tool

Book marketing professionals, I need your feedback. I've recently released a new tool (it's free to use) for creating smart marketing links for books.

The idea is that the links detects what kind of device your customers are using and what country they are from. Customers will be automatically redirected to the most suitable store to buy your books, be it the German Amazon store or a Swedish Itunes page.

You can find the service at: https://linkredirector.com

I'd very much appreciate if you would give me some comments on how such a tool would fit with your marketing strategy? And if you were to try it out and provide some feedback from your experience, that would be awesome.

Thanks,

Fredrik
