I use the slim armor from the same company and have had it for almost exactly a year. It's the only case I use, so I'm guessing this case will be just as well-made.
I got this one last week and i'm loving it. It's from Spigen: http://www.amazon.com/Galaxy-Case-Spigen-Slim-Armor/dp/B00I3UWD7C
Cant say I have. I wasnt a huge fan of the office. But a bunch of my friends have holsters. They always make the phone very accessible and frees up your pockets. I had a holster for my storm, my Droid X, my Nexus and i also got one for my S5. I wound up going with the Spigens Slim Armor case and I really really like it. I installed one of the tempered glass screen protectors with it
