Even better than the 4S version.,

This review is from: TuneBand for iPhone 5S, Premium Sports Armband with Two Straps and Two Screen Protectors (Black) (Wireless Phone Accessory)
So as the title implies, I own the 4S version of this workout case as well. The 5S version is more sturdy and comes with 2 bands for your choosing (depending the diameter of your biceps - raaaaaar!!).
The case itself is easy to slip on the phone and I use my existing screen protector (Tuneband includes one as well) and it doesn't peel up or anything. The case is thicker and sturdier and I've noticed the armband doesn't slowly "travel" from one side of my arm to the other like the previous model did when I run.
It's a simple and effective design and works perfectly.
