So, twister recently did a review of the same dock i had purchased for my note 2
Review of Monoprice Car Mount Cradle with charger for Note 2 w/lots of pics!!!
For those of you not familiar, twister has done some amazing reviews of different mobile accessories. Nonetheless, I wanted to post info on here to let people know that I received one of the ultra thin cases i purchased from ebay and so far, it seems like the car dock will work with the note 3, based on the case having no problem.
Of course, I'll have to update once i have the phone. The one thing I can confirm for sure is that it definitely won't work with thicker or bulky cases.
