Pros: Simple and durable design. Holds the bike tight, even at highway speeds and on bumpy roads.

Cons: Time consuming to mount and dismount at the trailhead. Expensive for what it does (I suspect patent royalties play a role in the pricing).

Recommendation: If you have a fork-mount rack and don't want to invest in a new system, this is the way to go. Yes, it's inconvenient and a little pricey but it's a good interim solution.
