I saw this on the Nickers website, it's neat! I don't know anyone who's used it but it's the same idea as the LG Zaum bridle so you might look up reviews on that.
Yes, it looks very much like an LG bridle/hackamore. I've used those - both just by the hackamore "ring" and those which have a leverage shank - they seem a good piece of equipment to me, allow precise signals and horses at our barn generally like them - however, horses that dislike poll pressure will not like them, and the shanked versions can be very harsh in the wrong hands.
