I do not claim to understand the technical side, therefore I do not claim to be able to explain the technical aspects of it.
However I know that the Remedy has an extremely good reputation and excellent reviews.
The bLINK is a new product and therefore I have not seen reviews, but honestly I have not looked for them either since I have no interest in Blue Tooth connections to my audio system.
I can say for sure that the Recovery does an amazing job. I know of several other members here who also have tried it and report how amazing it it. I can't try to explain how it works only that it does. EJ did describe how it worked to me, but honestly it was way above my head
