I've been pretty happy, the only thing I've noticed about them is they seem to be kind of temperature sensitive and I don't know if it's any more or less than other shocks. They do use an orifice for the adjustable portion of the damping and fluid viscosity is definitely a big factor in that type of valving (or any valving for that matter). Of course everything gets a little stiff and rattly when there's no degrees outside and that's what I'm dealing with now. If any of you in warm places want to send some degrees up here, we're running a deficit.
Really, I've been happy with the ride, they'll adjust from way too soft to way too hard, so you should be able to find a setting you're happy with.

I'd have to see what deals they have going on the shocks but they're usually right around $100 each.
