I now use for my Nexus 5 with Ringke Slim Case. Doubts arose in the selection of thickness ... the holder in the size 6-10mm but turned out to be the right one. The phone sits perfectly with the Case in the holder and there is no wiggle and squeeze.
I would recommend this bracket in full to all Nexus 5 owners with Ringke Case.
Only the price I find slightly overpriced.
For this reason, I would give the product 4.5 star!
