iPhone 5 Lightning Car Mount from Belkin -- Any Good?

I just came across the Belkin TuneBase AUX for iPhone 5. This looks pretty new as it is not even on Amazon yet. Can anybody tell me if they own it and it is decently built? It seems like the dearth in lightning-capable car chargers may be coming to an end. Part of the reason I have remained in the "S" upgrade cycle for iPhone is to ensure there are accessories like this available when I buy my new iPhone. However, even after a year of iPhone 5 being on the market it seems that accessory makers have been slow to add lightning in some form factors (like car mounts).

Are there other options similar to this that I am missing?
