I use Otter products for more than 4 years, my work requires a lot of physical activity and I must have my phone with me always, with Defender protector and its holder my phone is safe and very well protected without falling out of my pocket.
My work and lifestyle if very dynamic, robust if you will. The last thing I need is to have to worry about my phone's protection nor the ease and accessibility of it's use when I need it. I have always used the Otter box since I went to the IPhone 5, 6 and 6+. This is by far the best way to go.
