This is not a third party review of the effectiveness of this product.
Since they only supply devices to law enforcement, I doubt anyone will find such a review, but I don’t think that means we should believe the product doesn’t work, at least in theory it sounds quite feasible to me. There is some information available online given by law enforcement saying that the product does work, personally I think this is enough that we should believe it does work.
While I do agree with you, not everyone will agree on the authenticity of a particular source. I guess there is simply no way to be certain what their capabilities really are.
