I got the AC kones. They are the 2nd step up and the only ones I've seen in the store.
I asked an electrical engineer friend of mine about the ground controls and he actually thought the concept was pretty sound other than some of their specifics were absolute BS. His biggest concern was that the product didn't look big enough to peform the function they were intended to do.
He commented that based on the advertisements alone he'd probably choose them over the Sort Kones. I'm pretty certain that he'll approve of the Sort Kones once he gets a chance to listen.
