The unique feature of the "Rev-Turn" wrist support is that it allows the user's wrist to cup/uncup, cock/uncock, or both during the release, rather than locking-in those positions like most other wrist devices. It comes with three different slide tracks to change the amount of wrist cock/uncock, with the cup/uncup being adjusted similar to other devices.
I have not used one, and don't know if it offers any benefit, but these features are the reason for their price point in the market.
