I ordered the Flygrip Gravity for my GS4 the end of August. I liked it in all but I choose to carry my phone in a case attached to my belt. The Flygrip at that time made my phone too thick to use it. I just got a new case at the mall last week. This one has more room. I just check and I could make it work, but it won't slip in and out of the case as well. Also I put my phone in a cradle in the car while driving. The Flygrip makes the phone too awkward to rest properly in the cradle. So for me - it just does not work.
