Interesting product, first I've seen of it.
The number of times I've been working under the dash around the foot parking brake mechanism or catch the release handle in the face trying to extract myself from an un-natural position in my Camaro makes it temping.
As soon as it functions as well as a handle brake for setting the car up entering a corner or holding brake on steep hill to save the clutch it's a winner. Until then the handle brake wins in my opinion.
