Product is very helpful, you can strap your phone and run while holding it in your palm. Though one issue is of size. It is suitable for phones of size lesser than 5". These days most Androids are either 5"or bigger, it becomes tedious strapping them inside it.
this is a great little piece of kit no more slipping armbands or one that are to tight they stop your circulation .
fits your phone like a glove you can access the screen and even the camera without removing the holder(iphone6)
you can do the strap up so your not gripping the phone ,secure running in and out of traffic and crowds in London stays in place great for commuting runs
