This band is well studied, and appears willing Galaxy S5.
The build quality is good, and the neoprene is comfortable to wear, even if it's a little sweat.
The cuff has two internal compartments; one for the phone and one for what you want ..! I find it handy for storing my keys without scratching my phone. I still have a little room to put a small battery backup.
I like the Velcro tab on the side: it is actually useful to store the cord of my headphones, but mostly it keeps the zipper pulls, avoiding they waltz and sentrechoquent as I run.
Funny detail: despite the thick plastic, it is quite possible to control their smartphone through the window.
Finally, the price: 24,99, it seems correct for quality.
