Aduro U-Grip or Satechi CR-3600: anyone tried these car mounts?

[raino]

I'm looking to get a car holder/mount for my S3. The two that I've got my eyes on are the Aduro U-Grip and the Satechi CR-3600. Both are priced the same, and quite highly rated. I was wondering if anyone here had tried one (or both!) and had things good or bad to say. Thanks.
