Yes soam, I have it and it is a very worth while option but I'm not sure that it is worth $1,800 on its own.
In the UK it comes as part of a Package along with a wind deflector, steering wheel heating and through-loading system, all for £750. Well worth it for the comfort access and wind deflector alone.
One thing to note; it does not have the kick under the rear bumper functionality. Pity, because this is a good option to have.
Anorther thing to note; in the UK you cannot open the trunk from inside the car as the button located in the driver door has been omitted. Not sure if that is the case in your country as it is there on USA spec models.
Hope this helps. :driving:
